I waited and waited before posting this to the group : I am afraid of placebo effect.
But the cure given by Condor was really miraculous for me, in the specified time of 2 days.
Here is what Condor answered about my Parkinsons induced rosacea (red rashes on the face) :
"Your rash might be seborrheaic dermatitis, which is known to be common with PD. It can look similar to Rosacea.
Easily treated with anti dandruff shampoo. It cured me in two applications."
Thank you again Condor, and all of you for being part of this amazing group.
