One of the best known and most documented is echinacea. Also known as purple coneflower, echinacea is a herb which is not only safe to take but is also a potent stimulant of the immune system. Research has shown that echinacea not only activates and increases the numbers of T and B lymphocytes in the body, specialised cells which fight infection, it also has a distinct and powerful anti-viral activity. The root of the herb is considered to be the best source for medicinal efficacy, although the leaves also have a potent effect. Indeed, many echinacea preparations are derived from the whole of the plant offering the benefits of both root and leaf.
Treatment is simple.
Evidence shows that taking echinacea may speed recovery and reduce the severity of symptoms. Finally, besides using it when unwell, it is not uncommon for people to take echinacea as a preventive measure. However, note that preparations are most effective when taken intermittently. If you intend to take echinacea for long periods, for instance throughout winter when viral infections tend to be at their most prevalent in the general population, remember to take it in small quantities for only two to three weeks in each month.
