Personally, I do not particularly trust the tincture purchased in a pharmacy, since it is not known from which raw materials it is made and where this plant has grown. Therefore, it is better to purchase the seeds of the plant, grow it yourself. Next, dig the root and prepare the tincture from it. But you need to remember that it is impossible to take tincture from echinacea for tuberculosis, leukemia, allergies, scattered sclerosis, and during pregnancy. On the Internet you can find a lot of information on this topic and we hope that the treatment of psoriasis with folk remedies will help you.
