Similar to Airborne, but without the herbs or vitamin A. Contains vitamins B6 and B12 (good for the immune system), and 32 active mineral complexes.

VERDICT:

Pizzorno uses Emergen-C to ward off colds during family trips. “With all the viruses and toxins floating around, it’s important to support your immune and detoxification systems with these vitamins.”

Sinusitis

REMEDIES:

Nettle

This medicinal plant (in capsule, tea or tincture form) has anti-inflammatory actions; it can alleviate allergic conditions such as rhinitis (inflammation of the nose).

Neti pot

Using this nasal irrigation system (with 2% saline) improves sinus symptoms and reduces the use of antibiotics in treating chronic sinus problems.

VERDICT:

In Pizzorno’s experience, nettle is “only modestly effective” for sinus inflammation. Neti pots, however, are used in Ayurvedic medicine, as they wash viruses and bacteria off mucous membranes.

Parasites/ traveler’s diarrhea

REMEDIES:

Lactobacillus GG

Studies indicate that this strain of probiotic improves gastro- intestinal health by repopulating the intestinal tract with good bacteria.

Garlic

Several studies show that eating the antimicrobial raw garlic (preferably crushed or chopped) can inhibit a range of bacteria, including those resistant to antibiotics.

VERDICT:

Pizzorno recommends daily doses of Lactobacillus GG a few days before travel, then twice a day with meals during your trip. Garlic is less successful—in excess, it may start to kill good bacteria, too.

ALTITUDE SICKNESS

REMEDIES:

Ginkgo biloba

A couple of studies show that 160–180 mg of this herb—taken by capsule one day before ascent—can prevent symptoms of altitude sickness.

Coca
Many South American tribes chew the leaves and drink tea made from the coca plant in order to fend off oxygen deprivation at high altitudes.

VERDICT:

Evidence is weak for both these remedies. Pizzorno thinks one of the best measures for alleviating symptoms of altitude sickness is hydration—“Drink at least seven glasses of water a day.”
