Echinacea (Echinacea spp.)

About

Astragalus (Astragalus membranaceus), known in China as huang qi, is a perennial reaching about 16 in (40 cm), with hairy stems and compound leaves composed of multiple leaflet pairs. Its root has been used for centuries in traditional Chinese medicine, often with other herbs, and NCCIH says it is promoted to improve the response of the immune system. NCCIH says there is not enough reliable evidence to know whether astragalus helps any health condition.

Echinacea (especially E. angustifolia and E. purpurea) is a perennial promoted today for colds on the idea that it may stimulate the immune system; NCCIH says taking echinacea may slightly reduce the chance of catching a cold, but it is still unclear whether it shortens a cold. Native Americans used echinacea for respiratory tract infections, tooth pain and snakebite; NCCIH says it is unclear whether echinacea helps other health conditions, including eczema.

Safety & precautions

Skin Disorders & Acute Illness: It is generally recommended not to use astragalus during active skin disorders or acute infections. Individual Variation: NCCIH says astragalus may be safe by mouth but has not had a thorough safety evaluation, and that people with autoimmune diseases should avoid it. Use it with care if there are any underlying health issues, and it may need to be avoided in certain inflammatory skin conditions.

Allergy & Side Effects: NCCIH says echinacea is likely safe for most adults for short periods, but allergic reactions, which may be severe, can occur, and digestive upset is the most common side effect. It may also cause tingling in the throat. Autoimmune Disorders: Use with caution; strong immune stimulation might exacerbate certain autoimmune conditions. Mouth Sensation: Extracts often produce a scratchy sensation in the mouth or excess salivation.
