Chinese herbalists have been using bark, roots, seeds, and flowers to treat serious medical conditions for over 2,000 years. In modern times, pharmaceutical companies have made big money by isolating certain compounds from plants and replicating them synthetically. It is within this context that I want to highlight a new study from Harvard School of Dental Medicine that has isolated molecular properties in the Chinese herb Chang Shan, and found a use for it in treating auto-immune disorders like Multiple Sclerosis, Rheumatoid Arthritis, and Inflammatory Bowel Disease.
