Hi there i am looking for the medical herbal which has clinical evidence about its efficacy ?
I’d say morphine is pretty darn effective. And the vast majority if not all of the pharmaceutical morphine is actually extracted from poppies, not synthesized (total synthesis is possible but much more expensive). Actually most morphine extracted gets turned into codeine for pharmaceutical uses, but nevertheless, the morphine that does get put into pills and solutions, is 100% all natural!
Many. Colchicine, for instance, is derived the autumn crocus / meadow saffron. It is used to treat gout attacks, and is extremely effective in many cases, stopping the attack in 24-36 hours. Medical studies tend to focus on optimising the dosing protocol as it is toxic. The “herbal” form of the remedy goes back to ancient Greece
