Medical Definition of Echinacea

1. A commonly used herb for maintaining the immune system. There is evidence that use of echinacea can increase levels of tumour necrosis factor which is often already elevated in HIV positive people and may contribute to both wasting and the replication of HIV. Little clinical trial data are available on the herb's value in HIV and AIDS. (19 Jan 1998)
