The American Journal of Gastroenterology, (2 November 2010) just published a study that found a Chinese Herbal Medicine – the hemp seed pill – to be an effective treatment for constipation. Trial 1 determined the optimal dosage of hemp seed pill from among three dosages. Trial 2, a randomized double-blind study, compared 2 sets of participants (experimental and placebo) for 2 weeks and 8 weeks with an an 8-week follow-up. The group receiving the Chinese Medicine showed a statistically significant decrease in severity of constipation and straining of evacuation, and effective reduction in the use of rescue therapy when compared with placebo.
