Astragalus membranaceaus is a native to China and other areas of Asia and is a member of the Fabaceae (pea) family. It tastes sweet, starchy, slightly warm and moist. According to Lesley Tierra, astragalus has adaptogenic, diuretic, antiviral, cardiotonic, antioxidant and hepatoprotective properties. Astragalus has gotten a lot of press as an adapotgen and for helping people with cancer and rightfully so as it “…helps prevent immuosuppression caused by chemotherapy and has tumor-inhibiting activity”(Winston, 149). It is a personal favorite of mine for preventing and/or treating regular-old colds and related infections.
The Chinese name of this herb is huang qi, huang meaning yellow (the color of the root) and qi meaning leader, as it is considered a “leader” among the tonics in the Chinese pharmacopeia because it can be used by a wider range of people than other tonics like ginseng. Astragalus strengthens spleen qi to aid weak digestion, nausea and vomiting, bloating, assimilation and lack of appetite. It also bolsters wei qi (protective energy or immunity) and lung qi. Not surprisingly, astragalus has been adapted into Western herbalism because of its use in strengthening the immune system and aiding in defense of colds, flus and infections of the respiratory system.
Astragalus is usually sold in root slices or pieces. It is mostly prepared as a tea although it also comes n powdered and tinctured forms. To make astragalus tea at home, bring 4 cups of water to boil, add about 4 tablespoons of the root and simmer covered for 20 mins. Let cool slightly before pouring a cup or two and straining. It is quite palatable, and people don’t usually have a problem drinking 3 cups of it in a day. A little honey or a simmering a cinnamon stick along with the astragalus extenuates both the sweetness and the moistening quality.
I like to drink astragalus tea daily in the winter, often for a month or longer, when everyone around me is getting sick or when I feel on the verge of a getting a cold. Just recently my husband came down with a horrible cold. I knew I’d be next, so I loaded up on astragalus tea so when I got the cold myself it wasn’t that bad – just a runny nose without a cough or constricted chest. It also combines well with other immune enhancing herbs like shiitake, eleuthero, ginger and echincacea, and is safe for children, pregnant women and the elderly.
