Historical Properties & Uses
Chickweed has long had many uses in herbal medicine. It was well-liked by Native Americans for relief from such respiratory problems as bronchitis, whooping cough, colds, sore throat, and flu. In European folklore, chickweed was used for similar purposes, including treatment of tuberculosis.
Chickweed is often regarded as an undesirable weed by agriculture. However, clinical studies, although scanty, have documented its antibiotic properties as effective against certain respiratory pathogens.
Chickweed is also used by modern herbalists to treat rheumatism, gout, joint and blood diseases, eye inflammations, and hemorrhoids. The plant's high nutritive content may contribute to its potency.
Chickweed may also be made into an ointment for topical application in cases of eczema.
Method of Action
Chickweed has not been investigated to any extent, but it has been shown to have antitubercular activity.
Its nutrient content is quite high, yielding, for example, 150- 550mg of vitamin C per 100g of herb.
The British Herbal Pharmacopoeia recognizes chickweed as an antirheumatic; and topically as an antipruritic, vulnerary and emollient. Used in the treatment of rheumatism, eczema, psoriasis, indolent ulcer, and as a poultice for carbuncles and abscesses. Specific indication is topical as an ointment in pruritic skin eruptions.
