I grow an assortment of herbs for medicinal use as well as for my pleasure. There is a wealth of information on the internet for herbal usage but I will suggest looking at the resource links and always cross reference to verify the information. Here is one link...

The good thing about herbal medicine is it generally does not have the dosage strength so is safer than most meds.
People rarely consider one of the common herbs grown as an herb but it is and is medicinally common ~ Aloe barbadensis. This aloe plant will treat skin issues and help to heal wounds and burns.
Good luck in your quest. It is fun!
