By 220AD China's famous medical text The Huang Di Neijing Suwen Lingshu, the foundation text of all modern Acupuncture Schools, had been compiled. Medicine was changing. People believed in their ability to observe and understand the natural world, and that health and disease were subject to the principles of natural order. The Huang Di Neijing Suwen Lingshu, expresses the philosophical nature of this medicine, that the universe comprises of various forces, the opposing yet complementary forces of yin and yang, the five phases and how human health is a microcosm of these models.

It is during this same period that the Herbal texts Shen Nong ben cao jing (classic of materia medica), and Shang han lun (Discussion of cold induced disorders) were developed. The Shen Nong Ben Cao Jing was the first text to give individual properties of medicinal substances thus founding China's Materia Medica, a current format for modern texts.

Early texts contained 364 entries which has grown to 5767 medicinal substances of todays materia Medica. Herbal formulas may be perscribed in raw form to be boiled and taken as a soup, or in pill form for convienience. Both are available along with Acute diagnosis from Raglan Acupuncture.
