Yes, of course it took modern medical research practices to convert into a potent form, demonstrate its efficacy and combine it with other agents for maximum benefit against malaria.
But it also took someone - one person - to be willing to go against the tide of vicious contempt towards traditional medicine like that which has been on full display upthread here, and painstakingly study the ancient literature and see where it might lead.
That's one person who I'm quite sure would not ever have said anything like "I wouldn't mind if they weren't so insistent on preaching their bullshit everywhere they go and trying to pass it off as having any basis".
It's all very well to casually dismiss all non-mainstream remedies with "the problem is that overwhelmingly most of the time they don't", just as it's all very well to dismiss every new startup or technological innovation as being highly likely to fail. At least 95% of the time you might be right, but the time you're wrong is when it matters most, when you're talking about a new remedy for malaria, or, perhaps one day, a remedy for antibiotic-resistant bacterial infections.
Please just keep it in mind. Millions of lives saved already, because one person was able to suppress the temptation to sneer and let their curiosity win out.
