Here is an article about homeopathy...
From the article mentions that...
Homeopathic practice is based on a single law of therapeutics called the *Law of Similars*. This law states that *a substance that can cause the symptoms of a disease can also cure it*.
There is something similar in SriMadbhagvatam
आमयो यश्च भूतानां जायते येन सुव्रत
तदेव ह्यामयं द्रव्यं न पुनाति चिकित्सितम् |
This is from the fifth chapter of the first cento. And this verse would literally translate as ....
Whichever disease is caused in the living beings, by a given substance --
does that very substance, when therapeutically prepared, not cure that very disease.
