Walk into a Western health store and you might find St. John's wort for mood or valerian for sleep — each plant is typically used on its own, matched fairly directly to a symptom or condition. TCM works differently. A formula like Liuwei Dihuang Wan contains six herbs, but they are not six separate "remedies" for six separate problems. They are designed as a team: three herbs to nourish, three herbs to drain, chosen because the person using them fits a specific description — what TCM calls a pattern. For someone browsing an encyclopedia of Chinese medicines, this is worth keeping in mind: the ingredient list is best read after understanding which pattern the formula was created for. That is why every PCMWiki medicine entry includes a 'patterns' field and a contextual short description before the ingredients. The herbs themselves are only part of the story.
