Chamomile (Matricaria recutita) is commonly used in human herbal medicine as a mild sedative, and as an antispasmodic to relieve menstrual cramps. Both of these effects are contributed by one of its constituents, apigenin, which is one of the more well studied active ingredients in plant medicine.
Chondroitin sulfate is the major glycosaminoglycan (GAGS - see separate article found in this series) found in cartilage. It promotes water retention and elasticity in the cartilage, helping to ensure adequate shock absorption and adequate nourishment of the tissues that line the joint.
Coenzyme Q-10 (CoQ-10, CoQ10 or ubiquinone) exists in abundance in every human and animal body. It is an essential component of the mitochondria, which are the parts of the cell that produce energy from oxygen.
