Coal Tar Ointment Has Anyone Tried MG-217 Ointment On Their Psoriasis?

Has anyone tried MG-217 ointment on their psoriasis? - coal tar ointment

I have light, medium (?) Guttate on the legs, hips and animals and have wonderful things about MG-217 belongs, an ointment, coal tar. I took steroids and work during the time that I have, and then it's back to outbreaks.
I am aware that some things for some people and others less.
Can anyone tell me their experience with this product?

Thank you,
Andy
