Bitter taste receptors in the lungs & Hesperidin’s decongestant properties.

How did citrus peel help my symptoms? In several ways it turns out, potentially. Antiviral actions, decongestant ability within the lungs, and by reducing the risk of blood clot formation within the lungs as the viral load increases and more tissue damage has occurred.

The antiviral capabilities were mentioned in previous posts – hesperidin and neohesperidin may act as antivirals in several ways, the vitamin C also, and quercetin can act as a zinc ionophore. Zinc ionophores are like chemical taxi-cabs – carrying zinc into infected cells preferentially where the zinc then disrupts the viral replication. (this post) No viral replication, no cell bursting to release them to infect other cells, and so on, in an exponentially increasing level of viral load and dead cells for the patient. The dead cell contents can also become a health risk when occurring in too great a quantity for white blood cells to collect it all for safe detoxification and removal at lymph nodes and by the kidneys.

Decongestant action is due to the bitterness of the hesperidin, neohesperidin, and probably other bitter tasting phytonutrients in citrus peel, and also quinine & chloroquines (also bitter tasting). (19) Think of taste or other sensory receptors that can do a variety of different things depending on where they are located and what they are connected to. Receptors are like tiny machines, activate the keyhole/puzzle piece opening with the matching chemical agonist, or inhibit with the matching chemical antagonist, and then the machine will do something if activated, or not do something or stop doing something if inhibited.

The chloroquines and quinines were found to help relax the airway in people with asthma, and increase movement of mucus out of the lungs. Activation of the bitter taste receptors on immune cells led to reduced production of inflammatory chemokines and cytokines. (19)

Taste receptors on the tongue would be connected to nerve cells that tell the brain a bitter taste or other flavor type was sensed and that information would be used to eat more if hungry for the taste or to stop eating if satisfied. Taste receptors for sweet carbohydrates are much less sensitive, more of the sweet taste is needed to activate them, than bitter taste receptors, by a magnitude of thousands – one or a few molecules of a bitter substance might activate the taste bud in the mouth, while thousands of sweet molecules might be needed to activate the sweet taste receptor. Sour is somewhere in between in the amount of sour molecules needed to activate sour taste receptors.

In other areas of the body sensory receptors may be attached to other chemical pathways instead of to nerves that go to the brain. Within the lungs there are many bitter taste receptors which when activated signal the mucus lining of the lung cells to make thinner mucus and to increase the motion of the cilia. Cilia are hair like or tail like projections lining the cell walls that can all work together in a wave like motion to move mucus and any dust or virus or other infectious microbes up and out of the lungs. (2)

“Stimulation of these receptors by known bitter compounds activates calcium-dependent nitric oxide (NO) production that increases phosphorylation of ciliary proteins through protein kinase G (PKG). This increases ciliary beat frequency to facilitate the movement mucus out of the airway by increasing mucociliary transport rates. The generated NO also diffuses into the airway surface liquid & acts as an antibacterial defense mechanism. NO damages bacterial cell walls & DNA & may also damage fungal pathogens & inactivate viral proteins .” (Freund & Lee, 2)

Non-productive cough, a dry cough, feeling like something is in the lungs but you just can’t cough it out is part of the typical symptoms of COVID19/SARS-CoV2 infections for people who get sick rather than being asymptomatic carriers*. (*see footnote) To be able to have thin mucus that is protective, able to be traveled through easily by our mobile line of defense – the white blood cells, we need to have adequate water, and electrolytes (ions) within the cells: magnesium and potassium, and outside of the cells: sodium and calcium. Providing magnesium as a supplement (300 mg/day) helped thin mucus for patients with the genetic condition Cystic Firbrosis which causes chronic excess lung congestion. (16)

“Mucus is more than 95% water, making water and ions just as important for controlling mucus properties .” (1)

If a person also is having nausea and vomiting and/or diarrhea, at the same time or in progressive stages, then dehydration and electrolyte deficiencies may become a significant problem, even life-threatening if severe. See this post (ACE2…) for digestive tips, and this one for a way to bypass malabsorption of magnesium with a topical source that can be absorbed through hair follicles (which is how ancient people would have gotten plenty – fresh water sources uses to be rich in magnesium).

To activate the bitter taste receptors that help with forming healthy thin mucus and help activate the wave like motion of the cilia we would need to have some bitter chemicals that match the bitter taste receptors found in great quantity within lung tissue. Hesperidin is a tasteless chemical found in citrus peel, with a bitter tasting chemical side chain, (3), and neohesperidin, a similar flavonoid, likely is obviously bitter in taste. (26)

“Hesperidin, a flavonoid present in many citrus fruits, provides an example of a multi-domain compound. This molecule was found to contain eight of the substructures that form the nodes of the tree, and a selection of these are given in Figure 6. Of the eight node substructures contained within hesperidin, only one contains a significant proportion of known bitter molecules.” (3)

Anticoagulant action: The vitamin C and flavonoids in citrus peel can also help prevent blood clot formation which in more severely ill patients with COVID19 infections has been found to be part of the mortality risk. (4) Prevention is important – strengthen capillary walls to prevent microvascular damage that can lead to blood collecting and forming clots which then may block larger blood vessels and cause stroke like damage to larger areas of tissue.

More detail about this problem is available in a document with a revised Marik Protocol for treatment of ARDS with Vitamin C Infusion (and contains thiamine, vitamin B1 which may also be needed in greater quantity during a severe infection response, see this document 14, and 15). The revision recommendations are based on COVID19 treatment in China and elsewhere – the lung problems are not typical of ARDS and patients likely need more oxygen than pressure from the ventilator support or worse lung damage may result. (evms.edu/EVMS_Critical_Care_COVID-19_Protocol.pdf) (8)

Important Recommendation for Earlier Treatment for patients suspected of having a COVID19 infection – for homecare/outpatient prescriptions:

The evms.edu pdf includes a recommendation for nutrients to be used as a prevention before infection, and at home for early treatment (see the pdf for that list). Here is their recommendation for prevention dosing:

  • Vitamin C 500 mg BID and Quercetin 250-500 mg BID
  • Zinc 75-100 mg/day (acetate, gluconate or picolinate). Zinc lozenges are preferred. After 1-2 months, reduce the dose to 30-50 mg/day.
  • Melatonin (slow release): Begin with 0.3mg and increase as tolerated to 1-2 mg at night
  • Vitamin D3 1000-4000 u/day (optimal dose unknown). Likely that those with baseline low 25- OH vitamin D levels and those > living at 40o latitude will benefit the most.
  • (evms.edu/EVMS_Critical_Care_COVID-19_Protocol.pdf) (8)
  • Food sources of Quercetin include dock, sorrel, cilantro/coriander leaves, radicchio, kale, watercress, asparagus, onions, and okra: (graphic, via @HiperacusiaCAT), in addition to being found in citrus peel. (23)
  • Quercetin and EGCG are both are zinc ionophores that can carry zinc into infected cells preferentially where the zinc disrupts viral replication, and they may also have direct antiviral effects by inhibiting proteins that are important to the virus. The two phytonutrients may be even more effective at inhibiting the SARS-CoV2/COVID19 proteins than hydroxychloroquine and remsdivar medications based on computer modeling of the molecular shapes of the viral proteins, medications, and phytonutrients. (24)

Early treatment is critical due to the SARS-CoV-2 virus causing loss of iron from hemoglobin within red blood cells. In later stages of viral replication the lack of functioning hemoglobin alone causes lung damage due to the lack of oxygen. (20) Simply providing extra oxygen can’t help if there is too little functional hemoglobin. Providing blood transfusions with healthy red blood cells might be helpful – preventing the virus from replicating to that point would be better. *This theory was based on computer modeling and has not been verified. (25) The symptom of red blood cell’s having hemoglobin that is unable to transport oxygen is present in symptomatic Covid-19 illness, the theory about why iron is shifted out of hemoglobin was flawed.

Anemia of inflammation (post) could be the reason: the cytokine IL-6 causes an increase in hepcidin, which causes an increased movement of iron out of molecules of hemoglobin in red blood cells, or available for the growing red blood cells still within bone marrow, and into intracellular storage where it can overload the ability to keep it from oxidizing other chemicals and can lead to cell death. Pathogens also need iron so the strategy is a defense mechanism of the body that can become dangerous if the response becomes excessive. See the post Anemia of Chronic Inflammation, IL-6, Hepcidin, Iron, and Vitamin C, for more information.

A different group is recommending to the FDA to fast track approval for preventive, early treatment with zinc and an anti-malarial and an antibiotic that are fairly available and have a long history of use, so risks and dosing have been studied. “It’s important to note that HCQ, zinc, and azithromycin are very well understood drugs with clear safety profiles; they are widely available, generic, inexpensive, and can be scaled rapidly, including to the developing world, which would be expedited by US leadership in recommendations.” More is included in the second half of this post about the zinc and anti-malarial medication and other food/phytonutrient zinc ionophores which include quercetin. See this document for the recommendation to the FDA: (Immediate Treatment for Early Stage SARS-CoV-2 Infections). via (13)

Safety considerations of nutrient/phytonutrient Zinc Ionophore: Quercetin in very large doses may affect kidney health negatively (I can’t find a dose for that) however in an animal based study quercetin was protective of kidney health at a dose that would be about 360-720 milligrams per day for an adult weighing about 160 pounds (5-10 mg/Kg was provided to the experimental animals). (6) The amount of quercetin used as a zinc ionophore by a Canadian team may be 500 mg taken three times per day during or prior to suspected viral infection – but I can’t find the specific dosing. Zinc can be taken in larger amounts (~15-30 mg) for a few weeks but can collect in the body to excessive levels over time. Symptoms of chronic excess might include a decrease in immune function and copper deficiency may occur as the two trace minerals can affect each other (an excess of copper can cause a zinc deficiency). (Symptoms of excess Zinc, 7)

Bonus – Circadian cycles affect immune function – because bonuses are nice – another way phytonutrients, including hesperidin (9), may be helping immune function is by tipping the body towards the anti-inflammatory night-time chemistry and away from the daytime, stress response, inflammatory pathways.

And the bigger picture take-home-point from that is sleep is important for immune function and the sleep needs to have a complete blackout level of lighting for the body to be able to switch over to the anti-inflammatory action of an ancient dark night. We make more melatonin if we get some full spectrum daylight during daytime/wake hours and have complete darkness at nighttime – so a sleep eyemask or folded piece of soft clothing like a Tshirt draped over the eyes may help health. During my untested CoV-19 like illness I did have light sensitivity headaches and found sleeping or resting with a cloth over my eyes to be helpful.

Melatonin is a hormone that helps reduce inflammatory pathways that result in increased cytokines, and inflammasomes such as NLRP3 (10) which has been associated with worse prognosis for patients with COVID19. the role of NLRP3 activity in SARS-CoV (2003 strain) has been a subject of research. (12)

An animal study on oxidative damage from a type of cancer treatment: “Oral treatment with melatonin gel had a protective effect in the small intestine, which was associated with mitochondrial protection and, consequently, with a reduced inflammatory response, blunting the NF-κB/NLRP3 inflammasome signaling activation.” (10)

Phytonutrients that might inhibit NLRP3 and/or increase p53 activity.

Other phytonutrients including quercetin which is found in citrus peel, also can help inhibit production or activity of the inflammatory NLRP3 inflammasome. Sulfarophane (broccoli, etc), resveratrol (grape skins, etc), EGCG (green tea, pomegranate peel), curcumin (turmeric/curry powder), gensenoside (ginseng), emodin (aloe vera gel), mangiferin (mango) and genipin (from a fruit used as a Traditional Chinese Medicinal) are also phytonutrients that may reduce activity or production of NLRP3 inflammasomes. (17)

Increasing activity of a protein called p53 seems to help inhibit the production or activity of the NLRP3 inflammasome. Phytonutrients and nutrients that may promote p53 activity also include zinc, artemisinin (wormwood herb), goldenseal (berberine, also found in a few other herbs), Black seed oil (Nigella sativa), ginger (6-gingerol), feverfew, chamomile, and cordyceps mushrooms. (18) Replication of human coronaviruses and the SARS-CoV-1,(2003 strain) virus has been found to be inhibited by p53 and have also been found to cause the production of an additional protein that leads to breakdown of the p53 protein which may help explain the dysfunction of immune function in more severe infections. (21, 22)

Inactivating the NLRP3 inflammasome seems to have anti-inflammatory benefits (17) that may help prevent age related changes. It is an area of research being pursued for pharmaceutical development. (11) Sleep masks/pitch blackness during sleep, with the alarm clock and light leaking in the window covered, could help your body inactivate the NLRP3 inflammasome on a nightly basis with no ongoing copay. Options exist and are worth trying in an order of least toxicity risk to greater toxicity risk.

*Asymptomatic carriers: In some people the virus replicates somewhat but not to the point of much cell damage – not growing exponentially to the point of the patient’s life being threatened. Instead the virus seems to just become dormant within some cells and the person isn’t even aware they are sick – a symbiotic host/parasite relationship assures the parasite goes on living – in a living host – which is not abnormal, we typically have virus in us that can even provide some health benefits possibly – symbiotic means benefits both the host and the parasite, but not enough is known about this area of study – called our virome, (5), instead of microbiome.

Immune support against viral infection.

The concern about the Coronavirus outbreak is valid as the infection seems more dangerous than a winter flu season. People who smoke or have a chronic lung condition, or are elderly or have other chronic conditions, or who are obese, may be at increased risk of having a more severe case of Coronavirus.

*This blogpost is continued in a longer podcast / transcript, Fear and Immunity.

Symptoms can be non-noticeable or similar to a cold or mild flu. Digestive symptoms might occur in addition to lung symptoms, dry, non-productive cough, and chest pain, hot and cold feverish chills, and extreme tiredness. Smoking increases risk of lung symptoms developing into pneumonia. Recovery seems to take longer than for a cold or flu with some people needing hospital care for weeks with a ventilator for breathing. (World/national Coronavirus Statistics) Approximately 2-14 days from exposure to symptom onset, gradually developing symptoms with a cough and chest discomfort, fever, and shortness of breath/difficulty breathing being common symptoms. (Graphic by Robert Roy Britt)

Some people may be infectious without having developed symptoms yet, or at all possibly for the 20-29 year old age bracket based on South Korea’s more extensive testing of their population. (graphic-South Korea & Italy rates of COVID-19)

People seem to be most contagious before symptom onset and in the first week of illness. (link) Twenty days infectious is average and generally is reduced by the time coughing symptoms are over. Thirtyseven days infectious is the longest measured. (Zhou et al., 2020) Wearing a face mask while infectious might help protect others but is generally not recommended as necessary for people who are not sick. A Public Service video about reducing rate of infection by hand washing, staying home, focusing on not infecting others while we don’t know who might be contagious but not showing symptoms yet. (@thejuicemedia)

Contagion risk also seems worse than the flu or a cold as the virus can survive on surfaces longer than average, possibly a week or more. Respiratory droplets may be the usual route of infection however there also may be a risk of infection from an infected person’s bowel movement. Thorough hand washing with soap and plenty of water is more likely to disrupt the cell membrane of virus and remove them physically than depending on hand sanitizers which are designed for bacteria not virus.

Alcohol in the hand sanitizer may also be drying to the skin which also can increase risk of open sores which can allow infection to enter the body more easily. Moisturize with a hand lotion while the skin is still damp to seal in some of the water. Hand lotions don’t replace moisture, they add to an oily coating on the skin that helps prevent moisture loss.

Strengthening Immune Function – food and nutrients, rest, and water, cut down on sweets, increase positive thinking & stress coping habits.

*Nutrition is not a guarantee of not becoming infected with something but it can increase the likelihood of not becoming infected or not developing as severe symptoms, as seen in the Ebola outbreak (see embedded link) and with research on vitamin D and respiratory infection rate (see video link).

  • Sugar and high fructose corn syrup generally reduce immune health and may provide simple calories that support infectious microbes more than our own health. (Defeating the Coronavirus with Immunity & Hydrotherapy, Dr. Eddie Ramirez, Youtube)
  • Sleep helps the body recover and cope with healing or fighting infection.
  • Water is essential for the body to be able to have a thin protective layer of mucous in which white blood cells can more easily find and remove infected cells.
  • Positive feelings of hope and love are more likely to support health than fear and anxiety. Doris Day’s attitude in the song lyric may be more helpful, “Whatever will be, will be, que sera sera,” along with common sense health habits.
  • Vitamin C and/or zinc lozenges may be soothing for the throat and help immune function. Elderberry is also rich in antioxidants and may also be available in immune supporting lozenges.
An orange peeled so the white pith remains.
The orange zest layer of the orange peel can be trimmed to leave the white pith to be eaten with the sweet orange wedge. The white membrane is a source of nobiletin.
  • The white pithy membrane of an orange peel has beneficial phytonutrients and is also fairly mild like the inner peel of a pomegranate. Use a vegetable peeler or sharp knife to trim off just the outer layer of orange zest and then the sweetness of the orange sections will taste okay along with the white membrane.
    • The orange peel pith contains a phytonutrient, nobiletin, that may help with weigh loss too. (Orange Juice Molecule May ‘Drastically’ Reduce Obesity, Arterial Placque, slashgear.com)
    • Nobiletin is a chemical that promotes our circadian cycles and may be protective against metabolic syndrome. Genetic studies on animals suggest that differences in the CLOCK circadian protein can cause symptoms of metabolic syndrome – obesity, high blood lipids and blood sugar, low insulin levels, fatty liver, and respiratory uncoupling. (He, et al, 2016) Respiratory uncoupling changes the way mitochondria produce energy and if the changes continue for long may lead to worse dysfunction of the mitochondria which may lead to cancer (Seyfried, et al, 2014), or other chronic health problems. (Ruiz-Ramirez, et al., 2016) Research with nobiletin as a cancer treatment suggests that it stops cancer growth by deactivating cancerous genes. (plantmedicines.org)
    • Orange peel extract has also been studied for use against Coronavirus and it helped reduce replication of the virus. (Ulasli, et al., 2014)
    • Chen Pi, dried tangerine peel, is a traditional Chinese medicinal product sold as an anti-viral and digestive support. (alibaba.com/Chen Pi) Improving bioaccessibility of nobiletin with peanut protein nanoparticle encapsulation, for anti-cancer potential as a medication: (Ning, et al., 2019) Chen Pi is traditionally used as a digestive aid and for respiratory conditions that involve too much thick mucous. Chen Pi is thought to help thin the mucous and promote a more productive cough. (esgreen.com/Chen Pi)
  • Other immune supporting nutrients that may help against a Coronavirus infection include Nrf2 promoting sulfarophane and resveratrol. Elderberry is a good source of anthocyanins and other antioxidant phenols, blueberries and black beans would also be rich sources. Zinc and selenium are minerals with antioxidant function. (selenium sources) Having adequate Vitamin A and D is essential for immune function. NAC and lipoic acid are antioxidants. Nrf2 pathways increase our own internal production of antioxidants. (Other foods: Nrf2 Promoting Foods)
  • Both high dose vitamin C and zinc are listed as potential therapeutics for treatment of patients with COVID-19 and Chloroquine, the anti-malarial that was found helpful for treatment of the infection in China, is a zinc ionophore. (14) Zinc ionophores help with autophagy and apoptosis – the killing and engulfing of infected cells by white blood cells. (15)

Cytokine Storm Syndrome & Vitamin C Infusion, — webinar for medical professionals.

An over-reaction of the immune system called Cytokine Storm Syndrome or sepsis shock can be the cause of death from COVID-19 infection rather than the breathing problems and pneumonia symptoms. Some people may be more genetically at risk of having the inflammatory over-production of cytokines. (Cytokine Storm Syndrome/genetics) They are involved in killing infected cells but an excess can cause organ failure and lead to death. Intravenous Vitamin C Infusion can be safe and nontoxic for treating sepsis shock (Fowler 2014) and may improve survival rates (ScienceDaily) and is a strategy that was used in Wuhan, China for COVID-19 patients. (Video update by Dr. Cheng) (Clinical Trial/Peng) (Protocol used in China for Vitamin C Infusion IV treatment) A free webinar for medical professionals is being offered March 26 regarding Intravenous Vitamin C Infusion for COVID-19 treatment, see this for registration information. The webinar is now available as a video that can be viewed at any time, see the website: isom.ca. The Vitamin C Infusion technique is being used for COVID19 patients in a large hospital chain in New York, based on the improved survival rate seen in Shanghai China, (NYPost)

Patients from Wuhan with COVID-19 who were in the ICU had more cytokines, (“IL2, IL7, IL10, GSCF, IP10, MCP1, MIP1A, and TNFα.”, (Huang, et al, 2020)), than patients who weren’t sick enough to be admitted to the ICU. Other possible guidance to check for cytokine storm besides the cytokine levels is C-Reactive Protein and serum ferritin levels. (Teachey 2016) The medication Anakinra may be treatment. (comment)

From a nutrition care perspective – the Nrf2 promoting foods also tend to inhibit the inflammatory NfKb pathway which leads to increased production of TNFalpha and other cytokines.

Chloroquine phosphate, 500 mg BID, was used as a treatment in China per a comment on a medical site. (Detailed document with specific recommendations, may be helpful medication as a preventive or treatment.) It is an anti-malarial drug. and the virus seems to be interfering with heme in red blood cells, a little similar to malaria taking over red blood cells. ( Dr’s summary; and his ref list) Artemisinin is an extract of the herb woodruff that is used to treat malaria. It is available as an herbal supplement. (nobelprizemedicine/pdf)

With a new strain of virus we are learning how to treat it and how it spreads and being brand new, no one has immunity against it. Being a coronavirus puts it in the same group as colds and flus which can mutate slightly and we can catch the illness more than once.

The COVID-19 may also be able to be infectious to people who already recovered. (LATimes) The cases of reinfection may also be the same infection in the patient seeming to get better and then relapsing again.

Prevention is safest. Wash hands and surfaces thoroughly and regularly. Soap, water, and scrubbing physically helps break down virus membranes and remove the virus from skin and other surfaces. Hand sanitizer is not more effective than thoroughly washing with soap and water. antibacterial ingredients are designed against bacteria, not virus.

“Supplements thought to be useful in the prevention of coronavirus infection include NAC, elderberry, spirulina, beta-glucan, glucosamine, selenium, zinc, lipoic acid, sulforaphane, resveratrol, vitamin D, Bifidobacterium bifidum strain probiotics and sporebiotics. ”

Origins – not a bat in China, genetically traced to the US around Aug/Oct 2019.

*That link includes some speculation about origins of the current Coronavirus strain – supporting the immune system and reducing infection rate and severity of disease is necessary whether the strain was from bats in the wild or a lab or from a lab manipulation of a strain from bats – saving lives needs to be a goal now.

(statement from Robert Kennedy Jr) “He [Taiwan Virologist] demonstrated that only the US has all the five known strains of the virus (while Wuhan and most of China have only one, as do Taiwan and South Korea, Thailand and Vietnam, Singapore, and England, Belgium and Germany), constituting a thesis that the haplotypes in other nations may have originated in the US. Korea and Taiwan have a different haplotype of the virus than China, perhaps more infective but much less deadly, which would account for a death rate only 1/3 that of China. [*so infection rates from South Korea may not be represent the risk for all ares] Neither Iran nor Italy were included in the above tests, but both countries have now deciphered the locally prevalent genome and have declared them of different varieties from those in China, which means they did not originate in China but were of necessity introduced from another source. It is worth noting that the variety in Italy has approximately the same fatality rate as that of China, three times as great as other nations, while the haplotype in Iran appears to be the deadliest with a fatality rate of between 10% and 25%. (7) (8) (9)” (globalresearch.ca) (news stories). (transcript of a video) There seems to be at least two strains, more information is needed to understand the significance of that (abcnews.com).
