asked,
"No “parasite” at text in link" NIH doesn't recommend using nicotine as an anti-parasite. Because they don't know how α7 nicotinic acetylcholine receptor (α7nAChR) prevent parasites from going. Even know they used Choline to stop the growth of Sars-cov-2 and that report shows it works.
Took me 15 minutes to figure out how:
Choline(acyl group) Agonists(simulates) α7nAChR which is Quaternary ammonium cation (used to inactivate Sars-cov-2) synthesis (GPAT and LPAAT acyl transferases, phosphatase and choline phosphotransferase
Parasites thrive in acid phosphatase and can't reproduce in phosphatase. α7nAChR creates acyl phosphatase.
