Homeopathic medicine has no proven track record or certification process. There is also the issue of several quacks giving away placebos in place of medicines. Psychological factors are the root cause of erectile dysfunction in 10-20 percent cases, in which case, placebos might work, but that would mean that you didn’t need any medication in the first place. Allopathy is the best medicine, when prescribed under the guidance of a registered medical practitioner.
