.... On his advice my other half had chemo back in the UK, she had 4 drugs, 3 were artificial copies of natural remedies. If the drugs companies can't make money out of something they are unlikely to pay for research to prove that it works.
There is always not enough money to research everything, but the usual criteria for ranking isn't how much money it might make but how likely it is to work
If it works - pharma companies can make money out of it
We know this because - you've already stated that they do it
Anything that is naturally curative in nature is more convenient and often more effective once a company has worked out a way to mass produce it and put it in a shop
On the economic side, the idea of hiding a cure because they make more out of selling the treatment - just doesn't make sense economically
Because if every other company is covering up a cure - it means the one company that releases the actual cure gets a decades long patent and immediately takes all the money away from all their competitors
The only time when not making money stops research is when the entire market for a disease - are poor
This is why there's a whole branch called "neglected tropical disease" - these are all the diseases that it is not profitable for private companies to research because it wouldn't be guaranteed to get their research money back - so they rely on charitable foundations and government grants. it's worth noting the majority of all scientific research done worldwide is government grants and not private companies - for example even if zero pharma companies spent money on cancer research it would still be one of the most researched areas because of all the government grants that go towards it.
Unless anyone is planning on moving to deepest African then they're not really going to be affected by that
Anything that can be sold to comfortable middle class westerners will always be researched because it will always make money
And we definitely know this - because the Wellness alternative health industry makes more money than Big Pharma does
