3. Stimulant
Because of its astringent makeup, yarrow can be used as a tonic and a stimulant, able to stimulate the body’s own agents into serious action. This can be effective not only in the treatment of open wounds but also in the stimulation of some of the other workings of the body, such as in new skin production or new hair growth.
How astringent a plant or a herb is usually referred to how effective it is at sealing wounds and healing abrasions and cuts, but the stimulating nature of yarrow makes it all the more interesting and ultimately, all the more versatile in its potential applications. Some suggestions for its use could be to include it as part of a hair tonic or as part of an ointment to rub on to bald patches on the scalp.
If you needed any further proof of its value, you should try and find some in Red Dead Redemption 2 and explore just how versatile it is in that particular game!
