This herb, also known as snake root, is a very popular garden flower. It's a perennial and can grow up to 5 feet high.

Echinacea is easy to grow from seeds. It takes two years and it makes really pretty cone flowers. Grow Echinacea in fairly poor and dry soil in a sunny location.

Parts used: Rhizome, roots.

Echinacea is not recommended for people with tuberculosis, auto-immune diseases like lupus, rheumatoid arthritis, or multiple sclerosis. It's better if you take Echinacea for a short period of time (about two weeks), so that the body continues to be affected by it rather than fixated to its immune-stimulating properties.
