Marcy,
Thanks for the info, we're you able to find any info on the Miroestrol content?. I did some digging about verifying Miroestrol content, this is what came up. Btw, I have no interest in any brand of PM, my interest is being able to verify and answer the PM question I've had for the past few years.........why can't we verify current Miroestrol content from PM suppliers?.
P. mirifica containing food supplements sold as herbal medicines have been available to the general public in Thailand without prescription for over fifty years. Currently, only one company in Thailand does taxonomic field studies using experienced harvesters certified by the Thai Ministry of Forestry, combined with a HPLC fingerprint of the root to insure that genuine P. mirifica is used to make their standardized P. mirifica extract for world-wide distribution (Smith Naturals, Co., Ltd., Bangkok, Thailand). Standardization is determined by the following markers: miroestrol, diadzin, puerarin, genistin, daidzein and genestein. Further, the company has conducted extensive field investigations to learn when to harvest the plant and in what region at what time of the year and under climatic conditions. For example, immediately after a rain, the level of miroestrol/deoxymiroestrol drops significantly. The problem of substitution (mislabeling) is being addressed by the Ministry of Public Health in Thailand because the use of P. mirifica as an over-the-counter food supplement, regulated by the Thai FDA, involves more than 20 companies selling the product within Thailand.
Of some thirteen sub-species claimed to be Thai “Pueraria mirifica” only two commercial sources have been found to be genuine, the rest include P. mirifica containing little or no miroestrol, probably owing to substitution in whole or part with Pueraria candollei Graph. Ex. Benth or Pueraria lobata (Kudzu). Pueraria candollei Graph. Ex. Benth does contain miroestrol but little of the other phytoestrogens found in P. mirifica by HPLC. For this reason, a standardized P. mirifica root extract should be used supported by an HPLC fingerprint provided by the supplier along with a certificate of analysis for each lot.
