My husband has had bad allergies all of his life and has been on prescription anti-histimines since he was about 17 (he's 64 now). The homeopathic person that's helping him out put him on Quercitin. He is absolutely astonished that he has no trouble with allergies now. She recommended a particular brand which I guess I can't mention but it has 500mg of Vit C, 1000 mg of Quercetin, 140 mg Bromelain, 100mg Citrus Bioflavonoids, 25 mg Acerola, 25mg Rose hips and 20 mg Rutin. She recommended he take 2 a day. It seems it only took a month or so and he was allergy free. Now he only takes them once in awhile when he feels he needs them. He also takes MSM for his knees but it isn't helping much.

Yes for quercetin. I've tried a variety of things over the years--ACV, honey, nettle tea. They all were dubious. Maybe they helped some or maybe the allergen just went away after a few weeks.

One day I was desperate and looked on here to try something new. I happened to have some quercetin so I tried that. It may have taken a few days to establish itself, but after that, I'd just take one 500 mg in the morning and one in the evening... when I needed it. If I had slight allergies, I'd take it. Otherwise, not necessary. During the worst allergy season, I would sometimes take 3 a day.

Still had some allergies, but it works much better than any natural or conventional medicine I've taken.

Here is my supplement summary for what has helped me:

Multi-cure protocol/regimen

(1 capsule unless otherwise specified)
7 AM capsules: rutin (500 mg), prickly pear nopal cactus (650 mg), bamboo extract (300 mg), lutein (20 mg), ginger (550 mg), astaxanthin/zeaxanthin (4 mg each), hesperidin (500 mg), bilberry (300 mg of 4:1 extract), quercetin (400 mg), apple pectin (six 300 mg capsules), chicken sternum collagen type 2 (500 mg).

I take all of the 16 capsules/softgels with 1 tablespoon macadamia oil, put oil in mouth, add capsules and let capsules soak in oil in mouth a few seconds then wash capsules down with water.

7 AM powders (wash down one at a time with water): beef liver powder (1 level tsp), 1 level tsp inulin fiber, 1 level tsp dietary fiber cellulose, 1/8 level cup whole rye flour, 1 rounded teaspoon of beet root powder, 1/8 level cup unflavored whey protein concentrate or isolate.

10 AM boost - tuna DHA (500 mg softgel), marine phytoplankton (500 mg capsule), reduced glutathione (500 mg capsule).

Before lunch: 1 rounded tsp cinnamon powder, 1 rounded tsp beet root powder.

4 PM: 1 rounded teaspoon beet root powder.

8 PM: triphala (500 mg capsule), rosemary leaves (400 mg capsule), soy lecithin (1200 mg softgel), calcium hydroxyapatite (350 mg capsule), 1 rounded tsp beet root powder.

Comments: the nopal cactus healed my after meal itching/psoriasis on forearms and ankles within days, the hesperidin healed my gum pain and keeps my gums healthy, the calcium hydroxyapatite has type 1 collagen which feeds ligaments and tendons and so fixed my bending knee pain and also healed my sensitive teeth and therefore keeps my teeth, bones, ligaments and tendons healthy, the quercetin keeps my lungs and sinuses clear so I don't get chest colds any more anytime or in winter, chicken sternum type 2 collagen feeds cartilage and fixed my bone on bone knees rubbing and knocking around in their sockets and hanging loose while lying on my side and enabled a woman to no longer require a hip replacement after 6 months, bamboo extract seems to promote my fingernail growth and is 70% natural silica, beet root powder lowers blood pressure and dilates blood vessels with nitric oxide which allows me to wake up earlier like an oxygen supplement would and at a tenth of the cost of a well known beets product, whey protein concentrate gives my muscles strength and promotes my skin health/hair growth, liver powder promotes my stamina and has natural B-complex, macadamia oil cured my fungal toenail after 2 months or two 16 oz bottles at 2 tablespoons internally after meals and also dampens my candida stinging, while in the same time frame stopped some intermittent toe numbness & tingling (peripheral neuropathy), tuna DHA 500 mg increases my perception and well-being, plankton increases my life force, verbal fluency and increases my lung volume breath from it's RNA and my muscles' response to my lungs' oxygen intake, reduced glutathione is optimism in a bottle for me, rosemary promotes longevity as in the Italian village of Acciaroli near Salerno where the population of a few thousand has about 300 people who are aged over 100, presumably due to their high intake of rosemary, the soy lecithin softgel I have taken for 10 years before bed promotes sleep dependably and incredibly and is a nervous system relaxant from it's phosphatidyl choline and cured leg cramps in two people I know at 1 softgel daily.

for regularity: rye flour speeds bowel transit time, apple pectin congeals everything, inulin and cellulose add fiber. After being constipated most of my life, I took non-aluminum baking soda for 2.5 years at 1/2 level teaspoon in water morning and evening which cleansed and restored my bowels to regularity and baking soda is also very slick.

Cures I have had summary:

Skin itching/psoriasis- nopal prickly pear opuntia cactus Sore gums- hesperidin Knee pain- calcium hydroxyapatite (type 1 collagen) Sensitive teeth- calcium hydroxyapatite Knee/hip bone on bone- chicken sternum collagen type 2 Fungal toenail- macadamia oil internally Toe numbness & tingling- macadamia oil internally Chest colds gone- quercetin dihydrate Pessimism/brain fog- reduced glutathione Sleep- soy lecithin softgel Leg cramps- soy lecithin softgel

I have had horrible allergies for 20 years and have taken just about everything. At the health food store I came across Quercetin & Bromelain. The Quercetin helps with histamine production. The Bromelain (comes from pineapple) helps with sinus swelling. If you are allergic to pineapple you shouldn't take this. Also Vitamin C helps the immune system.

I just wish someone had shared this with me 20 years ago. It took about a week to work for me, but I now wake up every morning without headaches, grogginess, stuffy nose, or puffy eyes. This is what I have been taking and it has been life changing!

Quercetin - 500 mg or more

Bromelain - 250 mg or more

Vitamin C - 1,000 mg

In researching Quercetin, I also found that it's naturally occuring in foods like black/green tea, red onion, apples, red grapes, tomato, cranberries, spinach, broccoli, carrots, strawberries, blueberries and pears. I have also been eating more of these items as well.

Hope this helps,

UnaPiccolina

I noticed that I didn't catch a chest cold as I usually would have this winter.

Then I realized it was because I had taken 650 mg quercetin dihydrate daily. Quercetin also gives me energy.

My current capsule has only 250 mg and that might even be enough. Most quercetin products come with bromelain.

A person had really bad chest congestion and they started taking a Quercetin 250 mg tablet that had Ester-C and Bromelain daily and three weeks later their congestion is apparently gone.

For a year or two or more I would try quercetin for any lung or sinus problem like asthma, emphysema, COPD, pneumonia, bronchitis, sinusitis, etc.

The best value of quercetin that I know of is a 400 mg quercetin per capsule dose made by a major brand. It's actually listed as 800 mg quercetin with bromelain but that is for 2 capsules.
