This extract is therefore of utility in treating or alleviating pathological conditions associated with excessive or unbalanced snythesis of endogenous prostaglandins, for example, in reducing bronchoconstriction or treating arthritis. For this purpose, the extract may be administered by injection, by inhalation, or topically.
