Most of the RHO gene mutations responsible for retinitis pigmentosa alter the folding or transport of the rhodopsin protein. A few mutations cause rhodopsin to be constitutively activated instead of being activated in response to light.
Mix a few drops of Ravensara oil with tea tree oil. Add ample amount of a base oil, like coconut oil or olive oil. Apply this oil on cold sores, genital herpes and shingles lesions. Regular application 2 times a day provides great relief from the pain.
