I have tried both General A.J. Pleasanton's therapy recently, and the more modern Dinsha Ghadiali "Color Therapy" now used by Dr. William Campbell Douglass. (His booklet, Color Me Healthy available from Second Opinion).
After reading your online Gen. A.J. Pleasanton book, I immediately sought some blue glass but had to settle for painted glass and then blue transparent sheets wrapped around glass.
I am fighting a 2-1/2 year Zoster shingles PHN virus infection, and though there has been no immediate improvement in my condition, I am going to pursue this because of the extreme pain and the fact that pain medications do not stop pain, but do make me dizzy.
For explanation, Dr. Douglass (following Dinshah's method) uses different colors with light from either a flashlight or lamp, and uses different colors (and combinations) for different diseases.
I have used both methods, but have used Gen. Pleasonton's only twice, and will email you when I see some definite improvement.
It is not easy to find colored glass; such glass is all 1/4" thick, and of a rather small size. Only for Gen. Pleasanton's method have I used the sun for energy, but I think sunlight is necessary. (Both Dinshah and Dr. Douglass have had success, however, using flashlights and lamps.)
EC: Geraldine, thank you so writing in about this remedy. We are thrilled (to say the least) that someone is testing it! Hopefully many more people will try the blue glass and sunlight therapy so we can eventually get a feel for whether this is an effective remedy.
P.S. If anyone finds an online source for blue glass, please let us know.
