For pcos (testosterone excess),can we combine liquorice with peony in a 1:1 ratio, with daily dose of liquorice extract of about 50mg ?

Effect is uncertain: Effects and safety are uncertain unless the product is a real medicine, approved for use by the FDA, and backed up by good scientific studies published in reputable journals. Otherwise, claims may be just claims and nobody knows for sure what is really in the product, how much is in there or how pure the ingredients are. It means nobody knows how safe or not safe it is. That goes for most herbals.
