Scientific titleThe effect of herbal extract (EstroG-100) on pre-, peri- and post-menopausal women: a randomised double-blind placebo-controlled study
Study hypothesisA standardised mixed herbal extract of Cynanchum wilfordii, Phlomis umbrosa, and Angelica gigas was observed to significantly improve the menopausal symptoms of pre-, peri-, post-menopausal women without weight gain or any serious side effects.
Ethics approval(s)Sterling Institutional Review Board (IRB) (USA) approved on the 21st April 2009 (ref: IRB# 3192; NETESTROG-100-001)
ConditionMenopausal symptoms
InterventionQualified participants were provided with either EstroG-100 or placebo pill bottles. EstroG-100 (or FGF-271) is a standardised mixed root extract of Cynanchum wilfordii 32.5%, Phlomis umbrosa Turcz 32.5%, and Angelica gigas Nakai 35%.

The EstroG-100 tablet in the clinical study was comprised of 257.05 mg of EstroG-100, corn starch 164.56 mg, microcrystalline cellulose 186 mg, hydroxypropyl methyl cellulose 50 mg, titanium dioxide 15 mg, silicon dioxide 6.2 mg, magnesium stearate 6.2 mg, glycerin mono fatty acid ester 5 mg, and lac color 5 mg.

The placebo tablet consisted of corn starch 359.61 mg, microcrystalline cellulose 248 mg, hydroxypropyl methyl cellulose 50 mg, titanium dioxide 15 mg, silicon dioxide 6.2 mg, magnesium stearate 6.2 mg, glycerin mono fatty acid ester 5 mg, and lac color 5 mg.

Clinical study and placebo materials were separately formulated into 695 mg purple tablets. The pill bottles were packaged in identical bottles so that neither the research team nor the participants were able to differentiate them by appearance. Participants were instructed to take one tablet twice a day orally for 12 weeks.
