Allergy: Quercetin and Bromelain
July 3, 2009 | Leave a Comment
Quercetin and Bromelain
Two other natural products that may be worth consideration against allergies are quercetin and bromelain. Quercetin is an antioxidant flavonoid that is found in many fruits, vegetables, and herbs. The anti-inflammatory effect of quercetin helps stabilize mast cells. These are the cells in your eyes, nose, and lungs (and other places in your body) that are highly sensitive to allergens.
Think of mast cells as floating mines. When they come into contact with allergens like ragweed pollen or dust mite poop, a switch gets thrown on these cellular “mines” and all hell breaks loose. Mast cells start releasing histamine and other chemicals called kinins (pronounced KYE-nins), which then turn on a cascade of other nasty things like leukotrienes and prostaglandins. The end result is sneezing, itching, inflammation, and congestion.
Quercetin, especially when combined with bromelain (an enzyme derived from pineapple), seems to stabilize mast cells and make them less likely to trigger the release of such chemicals.44 45,46
We think such an approach may be more logical than trying to block the effect of histamine with antihistamines.
Think of it this way. If your mast cells are like a barn holding in a bunch of wild horses (histamine molecules), then what would be more efficient—reinforcing the door and walls of the barn to keep those wild histamines inside or trying to protect all the grass in your pasture from having those histamine “horses” nibbling away at it? Antihistamines are like a chemical barrier that tries to protect your grass once the horses are out of the barn. But they are not 100 percent efficient, and some histamine will always find a target and wreak havoc. Keeping the barn closed tightly (or the mast cells stabilized) seems to us to be a more effective approach.

Nondrug Allergies Treatment

Nondrug Approaches for Allergies
Even if you created a perfect living environment by eliminating carpets and rugs, minimizing stuffed furniture, banning your pets to the outdoors, and filtering your air, you could never truly eliminate allergens from your personal space. And every time you go outside, you are vulnerable to whatever is in the air. So, what can you do to minimize your reaction to pollen and all the other nasties flowing through your nose every time you breathe?
Nose Cleaning with Neti
Americans have a hard time imagining that you can clean your internal environment. But the Ayurvedic tradition of India encourages nasal washing with what’s known as a neti pot. This porcelain container looks a little like Aladdin’s lamp. It allows saltwater to be poured into one nostril and exit out the other. This washing process is supposed to clear the nasal passages of dust, pollen, and other allergens.
You can find neti pots at some health-food stores or by calling the Himalayan Institute at 800-822-4547. Visit their Web site at www.netipot.org to get an idea of what we are talking about. A ceramic pot costs $18 to $20.
For years I was troubled with allergies. But I have discovered the following natural approach. I use a ned pot to wash my sinuses with salt water Sinus and ear infections are now a thing of the distant past. Many people are grossed out at even the suggestion of pouring something into their noses, but the sensation is really very pleasant if done properly (with lukewarm filtered water and mild saline solution).
I also vacuum my bedding daily to get rid of dust mites.
Vitamin C
We are the first to acknowledge that vitamin C studies are squishy. There just have not been large, well-conducted clinical trials to test the effectiveness of ascorbic acid (vitamin Q against allergic disorders. The allergists will rightfully say that without decent data they cannot recommend this vitamin.
Nevertheless, some research suggests that this nutrient might help reduce allergy symptoms through a kind of antihistamine action.”,” There is also the possibility that vitamin C modulates immune-system reactivity and has anti-inflammatory effects.37 The benefits, if they exist, appear fairly short-lived. That’s why the general recommendation is to take 500 milligrams of ascorbic acid three or four times a day. 38
Stinging Nettle (Urtica dioica)
The very name of this herb is enough to scare many folks away. If you were to come into contact with stinging nettle, which grows widely throughout Europe and North America, you would have even more misgivings. Touching the tiny hairs on this plant can cause an impressive rash that can itch and sting for up to 12 hours.
It is ironic that these hairs contain a witches’ brew of ir-*** Stinging Nettle (Urtica dioica)
This herb is well known in Europe, where it is used primarily to relieve allergy symptoms and improve urinary flow in cases of benign prostate enlargement. The dose that has been used for treating nasal symptoms is 300 milligrams of freeze-dried Urtica dioica per day.
Side effects: This herb is usually well tolerated. Mild digestive upset has been reported, especially if it is taken on an empty stomach. Some people may experience an allergic. rash and should discontinue use immediately if this occurs. Downside: Large, well-controlled trials are lacking. Better research is needed before we can give this herb a ringing endorsement.
Cast: Approximately $5 to $10 for a month’s supply
ritating chemicals, including histamine and formic acid (also found in ant stings), yet the herb may be helpful in controlling allergy symptoms. When the leaves and other parts of the aboveground plant are extracted and swallowed, they may offer some fascinating pharmacological benefitS.39′
In Europe, where Urtica dioica is quite popular, physicians have been prescribing it to treat allergies for a long time. One double-blind trial noted that 58 percent of the study participants had good relief of SyMptoMS.41 Almost half of the patients said that stinging nettle was just as effective, if not more so, than their standard allergy medicine. Why something that contains histamine might actually help to relieve allergic symptoms is somewhat mysterious. Investigators suspect that it may help to modulate the immune response. 41
O. 1 feel like I am caught between a rock and a hard place. My allergies are awful, but most antihistamines and decongestants warn that they’re not to be used by men like me. I have an enlarged prostate, so Benadryl and Sudafed are off limits. Is there anything natural that would help my allergies and not aggravate my prostate problem?
A. Most over-the-counter (OTC) allergy medicines contain either an antihistamine or a decongestant that can make urination more difficult for a man with an enlarged prostate. An herbal remedy that might substitute is stinging nettle (Urtica dioica).
According to European research, extracts of this herb can do double duty to relieve allergy symptoms and help improve urine flow in men with benign prostate enlargement. Side effects are uncommon.
Now that the value of saw palmetto has been called into question for treating benign prostate enlargement (BPH) ‘42 some men may want to consider stinging nettle instead. Urtica dioica has been used to treat BPH in Europe for decades. There are good reasons why this herb might be effective. For one thing, stinging nettle root affects sex hormone–binding globulin and its ability to interact with hormones like testosterone. Another key player in prostate problems, epidermal growth factor, is inhibited by 53 percent by stinging nettle lectins. In addition, this herbal extract has anti-inflammatory activity that interferes with an enzyme (Na/K-ATPase) that is necessary for prostate cell growth.
Most important, human studies have shown that nettle root extract improves urine flow and decreases the amount of urine left in the bladder after voiding. Many men with an enlarged prostate report that the herb reduces the number of times they have to get up at night to go to the bathroom.
I read a letter in your column about a man with allergies. Because of an enlarged prostate, he couldn’t take the usual over-the-counter antihistamines.
You suggested the herb “stinging nettle’ as a substitute that might relieve allergy symptoms and improve the flow of urine. My husband looked these stinging nettles up and began taking them. He has improved 100 percent in both his allergy condition and his prostate symptom of frequent urination. In addition, his PSA number has come down!
The urologist said, “Yes, I’ve heard of it and it helps some but not others.” We are so glad you mentioned this herbal medicine, and we have shared the information with others.

Vacuum Cleaners
You can reduce dust and pollen with good air filtration, but you can never eliminate it. A decent vacuum cleaner can go a long way toward reducing the dirt and dust that can cause allergies. But many machines suck up dust and allergens at **** Miele Solaris Electra Plus
Choosing a vacuum cleaner is a highly personal: decision. We like this Miele machine because it comes with a HEPA filter, is highly rated by Consumer Reports, and has served us suc- cessfully for years. You may find the Sears canister vacuum just as effective at a substantially lower cost.
Downside: A little on the pricey side. Filter needs to be changed regularly.
Cost: Approximately $800
one end and spew them out with the exhaust at the other end. These vacuum cleaners may actually cause more problems for the allergy sufferer.
According to Consumer Reports, vacuum cleaner models “with a HEPA filter have been very effective at reducing emissions. However, some models that don’t have HEPA filters have performed just as well in our tests, and such vacuums may cost less than HEPA models.”34
The Sears Kenmore nmore canister models generally scored high in the Consumer Reports testing. The Progressive 25512 model, at $300, was a Consumer Reports “Best Buy.” Miele vacuums come with HEPA filters and range from $500 to $800. We have been very pleased with ours. The Bosch Premium, at around $800, and the Aerus Lux Guardian, at roughly $1,200, also come with HEPA filters and score well.
