the second paragraph of Wiki
"Claims to the efficacy of homeopathic treatment beyond the placebo effect are unsupported by the collective weight of scientific and clinical evidence.[4][5][6][7] Common homeopathic preparations are often indistinguishable from the pure diluent because the purported medicinal compound is diluted beyond the point where there is any likelihood that molecules from the original solution are present in the final product;[8] the claim that these treatments still have any pharmacological effect is thus scientifically implausible[9][10] and violates fundamental principles of science,[11] including the law of mass action.[11] Critics also object that the number of high-quality studies that support homeopathy is small, the conclusions are not definitive, and duplication of the results, a key test of scientific validity, has proven problematic at best.[12] The lack of convincing scientific evidence supporting its efficacy[13] and its use of remedies without active ingredients have caused homeopathy to be regarded as pseudoscience[14] or quackery.[15]"

So for you when you take it you dilute it by the method you discussed earlier? But now my first assumption would be that you are taking a very very low dose of these compounds and they are exerting some effect somewhere on something in your body (im going to ignore the placebo effect on this). Now how many dilutions would you normally do for example? Do you use the plant on a daily basis? The reason I ask is because I do think there are biologically active compounds in that mixture and although they are dilute thats a good thing! Because they are toxic at higher doses. Thats what I am curious about. I find it hard to believe that its so dilute that nothing is left. These are potent alkaloids hence why they are dangerous they must be diluted to be safe.
