Dr. Loretta Lamphier in my Yahoo oleandersoup health group has pointed out this encouraging information:

Although I am one of the very last people to ever recommend mainstream treatments, this one may be an exception in some instances. It has impressed me as one of the safest and most effective ones around.
If you should choose to use it, I would recommend making sure that you protect your liver with milk thistle, alpha-lipoic acid, selenium (the three anti-oxidants used in the Berkson clinical study) and possibly oleander and colloidal silver.
