Where do we find records of Clematis ? In Stapf's Archives and in Hahnemann's Chronic Diseases. Provings of the Austrian Society . What is this drug ? This is the Virgin's bower , a European plant ; the tincture is made from the roots and stems in the same manner as described under Aconite , and should be imported. What is our principal use of the drug ? In orchitis of gonorrhoeal origin, and when the testicle in indurated and hard as a stone and very painful. Compare it with Rhododendron. In Rhododendron the testicle tends to atrophy ; there is a crushed feeling in the gland, and it is more useful in chronic cases ; both drugs have pains which course up the spermatic cord.
