Important warning for allergy sufferers

I love springtime. But many of my patients dread this time of year…

They come to my clinic sneezing and sniffling. They have runny noses, and watery, itchy eyes. They can’t sleep or work.

You may have the same problems. You need relief fast to get back to your life. So you might be tempted to pop some OTC remedies or ask your doctor for a prescription.

But you may be getting more than you bargained for with those allergy drugs. They may make you lose your mind. Let me explain…

Many doctors treat allergies with a class of drugs called (ACs). You know them by names like Benadryl and Dimetapp.

In a new study, scientists linked ACs to an increased risk of dementia.1

Researchers at the Indiana University School of Medicine looked at 451 people, with an average age of 73. Sixty of the patients were taking at least one AC drug.

They gave the whole group memory and cognitive tests. They did PET scans to measure brain activity. They did MRI scans to measure changes in brain structure.

The results were worrying…

The people taking AC drugs did worse on short-term memory tests. They had worse verbal reasoning, planning skills and problem-solving.

They also had lower levels of brain activity, especially in the hippocampus — the region of the brain linked with memory. And they had reduced brain volume and larger cavities or holes inside their brains.

In other words, people taking the drugs had more brain atrophy.

And AC drugs cause damage quickly. In fact, using these drugs for as few as 60 or 90 days can cause cognitive problems.2

Allergies are your immune system over-reacting to normal dust, pollen and animal fur. Special cells in the blood vessel linings of the inner eyelids, nasal membranes, and lungs release substances called histamine and inflammatory prostaglandins. These are the real culprits behind all the misery. They release fluids to flush out what your body
thinks is a viral or bacterial infection.

I don’t prescribe those dangerous AC drugs for allergies. Instead, I help my patients relieve the symptoms naturally.

5 Natural Allergy Busters

1. Neti Pot. This Ayurvedic therapy irrigates your sinuses. It flushes allergens and irritants out your nasal passages. You can find neti pots in your local health food store.  Just follow the directions on the box. But one caution… make sure the water is distilled and as sterile as possible. Tap water is full of chlorine and fluoride. That can
actually aggravate your sinuses.

2. Pineapple. This tropical fruit contains an enzyme called bromelain. It counteracts the effects of inflammatory prostaglandins. To help lessen inflammation, you’ll need to eat about a cup of fresh pineapple every day.

You can also take a supplement. Look for a capsule that is at or near 2,400 GDU, the highest standardized potency you can get. I recommend you take 400-500 mg a day.

3. Quercetin. This bioflavonoid targets the special cells that make histamine. Studies show it prevents allergies before they start. It can even stop allergic reactions in progress. And it works instantly.3

Quercetin is found naturally in many fruits and vegetables. Try eating more apples, broccoli, cherries, citrus fruit, cranberries, green tea, leafy greens, raspberries, red grapes, onion, shallots, and tomatoes. If you’re prone to allergies, start eating more of these foods a few weeks before spring arrives. Or you can supplement. I recommend taking 500 mg
twice a day.

4. Stinging Nettle (urtica dioica). This prickly herb is a natural anti-inflammatory. It can prevent hay fever symptoms if taken as soon as they appear.4 It works by balancing histamine levels and preventing the production of prostaglandins.

I recommend drinking nettle tea. You can find dried leaves or tea bags in your local health food store or online. Drink one or two cups a day with a meal.

5. Vitamin C. You already know vitamin C boosts the immune system.  But it also halts the production of histamine. And it speeds up the breakdown of histamine already in the blood. One study showed that taking 2,000 mg of vitamin C per day lowered histamine levels by 38% in healthy adults — after just one week.5
