How long will it take for the homeopathic medicine to cure astigmatism please let me know?

Unfortunately homeopathic "medicine" will not cure anything, it is nothing but water. I don't know how this quackery ever found it's way back into popularity. Not only is the concept totally implausible, there is no clinical evidence of efficacy beyond placebo. None. If your daughter needs medical attention, best you see a proper doctor.

Homeopathic 'medicine' won't cure astigmatism. See a real doctor.

Basically homeopathy involves taking a chemical and diluting it many thousands of times in water. It is diluted so much that only a few molecules of the effective ingredient remain in the water. If you take a homeopathic remedy you are taking WATER (or water in a sugar pill). Homeopaths believe that the 'vibrations' or 'memory' of the effective ingredient remain in the water and that is what gets your body to cure itself. This is scientifically ridiculous and has been conclusively proven not to work. You'll hear from many people here who believe in this treatment and even from some who have studied for years to be homeopaths. I do not doubt that they believe what they are saying/selling, but it has been conclusively proven in scientific trials to be not only ineffective, but scientifically impossible. Please do not be fooled into wasting your money homeopathic treatments, especially when you have children who could use the money much more. Please get your child proper treatment from a real doctor or ophthalmologist. "when you buy homeopathic pills sold today, you're actually buying sugar, water, or alcohol that's "channeling" (for lack of a better term) some described substance. The substance itself no longer remains, except for a few millionth-part molecules in the lowest dilutions." http://skeptoid.com/episodes/4034 "Several rigorous trials of homeopathy in human medicine have been performed in recent years. According to these randomized, placebo-controlled, double-blind trials, homeopathic "remedies" are not effective" http://www.acsh.org/healthissues/newsID.632/healthissue_detail.asp "none of the studies that have generated positive findings has been replicated with such findings, the methodological quality of these studies has been questionable, and the better studies of homeopathy have tended not to generate positive findings." http://www.acsh.org/healthissues/newsID.632/healthissue_detail.asp

Can't be done any more than growing a new leg after one has been cut off.

How long? Hmmm. A million years. Please see a real doctor.
