So I ordered a pound of walnut leaves on impulse because that so far appears to be the only plant where progesterone (and not just a precursor of it) has been documented. I have no idea how much progesterone is typically in walnut leaves because the scientific paper everyone refers to is behind a paywall. I also don't know what to do with the leaves.
The leaves come dried and shredded to be used as tea. According to Wikipedia the melting point of progesterone is 126°C and it is not soluble in water, so I don't think much of the progesterone would pass into the drink. I definitely don't want to use ethanol to dissolve it. Or should I simply eat the leaves? Mixing half a gram of PM powder into my morning cereals doesn't affect its taste.
Since Dr. Powers believes up the butt is the best way for progesterone, maybe grinding it to a powder and mixing it with coconut oil before cooling to make suppositories? I could also add the PM I'm currently taking orally... Or would it be better to heat the mixture first above the 126°C? When does progesterone evaporate or break down?
