Apologies. Presumably those thousands of clinics etc in the search results "posit that palm reading is legitimate medicine". I had to guess what your question meant exactly - as is, it's not grammatical english, and is ambiguous in at least two ways. I should've asked you to clarify instead, or just not tried to answer.

Not really, they're more astrology based, not medicine, and no one is claiming astrology is factual in this thread. Also, they're clinics, not a source of any kind which is what was asked for.
