I have been taking the Tang Kuei tablets for several weeks (and Seven Forests Tang Kuei 18 before that time) along with with acupuncture treatments while trying to improve my overall health, and with the eventual goal of becoming pregnant-- i tend to be "cold and damp", particularly when under stress. I have experienced great results in the course of the last several months of treatment: my pulses have become much stronger and my acupuncturist tells me that my body has warmed significantly! I would happily recommend this product to others with similar issues.
