A great psoriasis cream with arnica, Goodbye Body Butter by Green Therapy is a superior choice to over-the-counter psoriasis medication with it's blend of essential oils, natural herbs, and homeopathic ingredients.
Personally, a have a nagging bit of eczema on my finger, I've tried every sort of moisturizer or product and finally went to a doctor for prescription strength cream. It happens monthly and the medication has been working fine. Until it ran out.
I wouldn't have thought to use a marijuana infused topical lotion for psoriasis, but it was on hand (pun intended) and I needed relief. I can't say that it was as effective as the prescription strength cream, but I was impressed how well it worked! It took 2 application to the affected area, and the dry, cracked skin healed up fast.
The manufacturer insists that success like I had for eczema has been reported by people suffering from psoriasis.
