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.
The oils I used most were sage, ylang ylang, geranium, EndoFlex, and Lady Sclareol. I would fill my palm with carrier oil and then add 3-4 drops of essential oil (usually just 1 oil or blend, but sometimes would mix 2 oils together). I would rub that on my lower abdomen, lower back, and neck.
