"I have found Collinsonia (Stone Root) to be of great
reliability in assisting to stabilize the lining on the sinus cavities and to
minimize the build-up of excess mucus in the sinus cavities and throat."
-Peter J. D'Adamo, N.D.
Collinsonia or "stone root" (other common names have included knob root, horse balm, and richweed) has traditionally been employed for passive venous congestion or engorgement. It was historically described as astringent, alterative, diuretic, tonic, etc., none of which give a very clear idea of its effects. A more apt description of its actions in old herbal texts often emphasizes its ability to overcome undue congestion with accompanying pain, irritation, and a sense of stagnation, whether it is within the rectum, pharynx (throat), or other vascular area. In the Merck Index its active principles are listed as resins, saponins, tannins, and mucilage.
