I read that to much eggplant is bad for Qi/Chi/Ki and was wondering why? Also, my finances are limited re: book mentioned by moderator before... What supplements are good for Qi? Is ginseng one? Also, there were references to ancient masters smoking herb, although understandably not socially/politically correct does it objectively have an effect on Qi? I understand it slows reaction time and therefore is not advisable for obvious reasons, but is the "fiery hemp plant" considered one of them. In the "Barefoot Doctor's manual, the only reference was the seeds can relieve constipation.
