HN really upvotes some dumb medical articles, come on, n=20 about peppermint?
cuz if so they may have more reason to sell than the bloody mint oil
Also, peppermint oil is unpatentable. Neither Merck nor Novo Nordisk can hope to make billions from it, and without the profit motive, the list of institutions with both the budget and the will to fund a 500+ participant study is pretty short. This might be the best we can get.
And yes, I get that a small trial has less of a value...
New word of the day!
