Among practitioners outside the mainstream, many true inheritors of Chinese medicine revere Zhongjing's classical formulas.
They know that as long as Xixin is used in a decoction and boiled at a high temperature for an extended period, most of its volatile oils dissipate, greatly reducing its toxicity and making larger doses safe.
As the renowned Qing dynasty physician Zhang Xichun once said, Xixin's fragrance is exceptionally strong. It is adept at opening up knotted qi, dispelling stagnation, reaching upward to the crown of the head, and circulating throughout the entire body.
Internally, it can open the Collateral Meridians of the organs; externally, it can circulate qi and blood to permeate the very skin.
