Herbs are widely used in China, often in combination with acupuncture. There are thousands of varieties, all of which are extensively described in the extensive materia medica.
There are also very old “formulas,” a “collection” of herbs that support each other and, taken together, have a significant impact on health. Acupuncturists who use herbs must have undergone thorough training.
Nowadays there are reputable companies that guarantee the quality of the herbs.
