AH ha.. Psoriasis is a skin condition. Now is a good time to get your moneys worth out of your new Ozone machine. I would make and have on many occasions a nice big batch of ozonated gel. Preferably out of Macademia nut oil.
Macadamia nut oil is higher in Mono unsaturated fats than the old tried and true Olive oil. I have Bubbled Maca oil for less than 72 hours and have gotten a gel thicker than Vaseline.Fully Ozonated Maca oil will kick psoriasis's ass out of town. I have personally seen melanoma peel right off the face of a friend with skin cancer. It takes few weeks before the therapy really kicks in.
