The page cites WebMD on bromelain, and the safety section of that reference is the part buyers most often skip.
Read the side effects and interactions sections, especially any mention of blood-thinning medication. The site's own footer already flags that Ginger Root and Bromelain have documented interaction potential.
If anything on that page applies to you, talk to your pharmacist or doctor before ordering. A reference you only skim for support is not doing its job.
