L-Lysine + Echinacea 是老外對抗病毒的一種常用方法。。。

Lysine

Lysine is one of the nine essential amino acids your body needs to grow and function properly. It is especially important for the production of carnitine, a nutrient that reduces cholesterol and helps convert fatty acids into energy. Lysine also helps with calcium absorption, as well as the formation of collagen, the main protein in your skin, bones, tendons and cartilage. Lysine abounds in meats, dairy products and legumes, but you can also get it from dietary supplements. Besides its essential roles, lysine may reduce blood sugar, as well as prevent or treat herpes simplex infections, high blood pressure or rheumatoid arthritis, reports Drugs.com.

Echinacea

The National Center for Complementary and Alternative Medicine describes nine species of echinacea in the United States and southern Canada. Among these, E. angustifolia, E.pallida and E. purpurea are the most commonly used in traditional medicine. You can find them as extracts, tinctures, tablets, capsules or ointments. According to the University of Maryland Medical Center, echinacea's active ingredients have hormonal, antioxidant and antiviral properties. Echinacea can also boost your immune system and help treat skin disorders, the common cold and herpes simplex infections.

Supplement Combination

Lysine and echinacea both act as immune-system boosters and can occur in combination, along with other herbs, vitamins and minerals. Some multi-nutrient formulas, for instance, combine lysine, vitamin C, echinacea and garlic for increased benefits. Possible complementary effects of such supplements include improved metabolism, anxiety and mental stress reduction and enhancement of immune and cardiovascular activities.
