“Different types of herbs are also recommended for treating different types of spleen imbalances and particular gastrointestinal disorders. Bian advises codonopsis root (called dang shen) and astragalus root (huangqi) for deficient chi, and dried ginger and aconite root for deficient yang. Specifically, Bian says, “the hemp seed pill [HSP] … has been used to treat functional constipation”.
Bian cites a 4 1/2-year study by Baptist University, published last year in theAmerican Journal of Gastroenterology, which found that high doses of HSP were more effective than low or medium doses in easing constipation among 96 patients.
A subsequent placebo test – in which the patients were split into placebo and HSP groups – reinforced the strong effects of HSP. Results showed the efficacy of the pill was higher than those in the placebo group. The pill is a mixture of hemp seeds, rhubarb, apricot seeds, white peony root, magnolia bark and immature bitter orange.”
