Alpha Herb Works?

So i’ve came across this indonesian herb that people call "alpha herb", looks like it makes you last a lot longer in sex, and i have some premature ejaculation issues.

Here’s the link: https://www.ama … /dp/B07LFJMB2S/

Anyone here tried that and can tell me if it works? I wouldn’t mind if doesn’t end up working if i buy one because it’s cheap, i’m just afraid that i will have problems if i spray that thing in my glans.
