In this episode, Yefim Gamgoneishvili and Jason Robertson discuss the much-debated question regarding 'tonification/補 bǔ' in acupuncture. Specifically, the question often arises regarding whether or not we can actually tonify using acupuncture (or moxa) or whether 'true' deficiency requires herbal medicine or dietary supplementation.  In this episode, Yefim also discusses how a practitioner might assess whether a given point is in a state of 'excess' (實 shí) or 'deficiency' (虚 xū).
