That's not the contention. The contention is that concoctions that have been developed by people who have experimented with home remedies for centuries should be clinically tested (e.g. by administering to someone with a drug-resistant fungal infection) to see whether they might be effective.
That's why I didn't mention the pharma companies. If it legitimately helps people there's still tons of money to be made off of it, such as marketing it properly and some optimized form for consumption - like how Epipen scammed the public with their 'form factor' patents which held up generic brands for years.
