BL-27 Xiaochangshu, the Back-Shu point of the Small Intestine, is a master point for separating the pure from the turbid. In Chinese medicine, the Small Intestine is responsible for sorting through the food we eat, separating the useful nutrients from the waste. On an emotional level, it helps us to sort through our thoughts and emotions, deciding what to keep and what to discard.

Think of Xiaochangshu as a point of discernment and clarity. It's especially useful for digestive issues like abdominal pain, diarrhea, and bloating that are caused by the body's inability to properly sort and absorb nutrients. On an emotional level, it helps to alleviate a scattered mind, promoting a sense of mental clarity and focus.

By supporting the Small Intestine's function, BL-27 helps to restore a sense of order and clarity in our lives. It's a point that reminds us that true health comes from the ability to distinguish between what nourishes us and what holds us back.
