Onion
Many ancient cultures believed in the healing and preventative powers of onions. Even ancient Greek athletes used them prior to competing. Over the years, a number of these age old theories have been put to the test, and more often than not they’re proven true. The sulfur compounds in onions can reduce the symptoms of diabetes, and they’re loaded with quercetin too, which prevents inflammation and helps prevent a number of different cancers.

Cayenne Pepper
Used for anything from pain relief to aphrodisiacs, cayenne peppers have been a staple of the “new world” since Columbus brought them here. These peppers get their heat from capsaicin, and that’s also where the pain relief aspect comes in. Studies have shown that it reduces the chemical reaction that sends pain messages to and from the brain.

Plantain
Not to be confused with the banana-esque tropical fruit of the same name, this plantain dates back to the 12th century as a poultice for everything from insect bites to wounds and burns. The plant has numerous antimicrobial properties that can help heal the skin and sooth burns and bites. The seeds are also used as the fiber source in laxatives.

Parsley
Dating back to 1629 when it was recommended and prepared for the Queen of England, parsley root has been used for health of the urinary tract. This benefit can be accredited to its ability to increase urine output. For the best result, drink tea made with parsley three times a day, or eat parsley leaves regularly for long term benefits. The chlorophyll in parsley also makes it a good breath freshener.

Watermelon
The high liquid content of watermelon, along with the natural sugars and fiber, make it the perfect snack. However, it’s much more than just a snack. Tomatoes are highly touted for their high content of the immune strengthening antioxidant lycopene. The fact is that watermelon actually contains more lycopene (40% actually) than tomatoes. If you bring one home, keep it out even once it’s cut instead of refrigerating it. This may sound strange, but you get the most benefit this way. Room temperature watermelon can continue producing antioxidants for up to two weeks.

Onions
Primarily used for seasoning, onions are high in vitamin C, fiber, folate, and vitamin B-6. They also contain large amounts of quercetin, which can help relieve allergies and has also been known to have anti-cancer effects. Studies have shown that people who eat the most onions can reduce their risk for oral cancer by 84%, colon cancer by 56%, breast cancer by 25% and prostate cancer by 71%. Red onions have the most quercetin, but pink shallots have a wider mix of antioxidants.

Lettuce
Looking at the light green color of most lettuce would generally lead one to believe that it doesn’t have the nutrients of other vegetables, but this is not the case. Iceberg lettuce contains lutein and zeaxanthin, which are carotenoids that reduce the risk of cataracts and age related macular degeneration. Add a salad at the beginning of a meal to get some of these benefits, and you’ll also likely eat fewer overall calories due to feeling more full and satisfied.

There are over 40 million Americans that suffer from seasonal allergies, and what’s worse is that most of the medications that help alleviate these symptoms have harmful side effects. Fortunately, there are some answers hiding in nature that are much safer than drugs, and have little to no side effects.

Quercetin
Quercetin is a plant pigment that can inhibit cells that produce histamine.  It’s naturally occurring, and can be found in various foods like citrus fruits and onions. Don’t plan on getting enough of it through your diet though, the amounts found in foods can be minimal. Depending on the severity of your symptoms, take up to 600mg of a quercetin supplement either preventatively or once your symptoms start. It has minimal side effects like headache or upset stomach in some cases.

Stinging nettle
Stinging nettle is a flowering plant that reduces histamine production when ingested. The average dose is between 500mg to 1000mg depending on the severity of the symptoms. Consult your doctor or allergist first, as some people can be allergic to stinging nettle. Rare cases can cause upset stomachs.

Fish oil
The same omega 3 fatty acids that can reduce inflammation that leads to heart disease also helps with allergies. When buying fish oil, be sure to read the label carefully. Make sure you’re getting mercury free fish oil that is either purified or pharmaceutical grade. This will ensure that what you’re buying is potent enough to have positive effects and has had any and all potential toxins removed. Typical dose is 2000mg a day.
