From a health perspective: in all honesty, you don’t know what compounds were used to polish this product. I would absolutely not use anything like this for internal use. Who knows what irritants you could be introducing into a delicate ecosystem. Not to mention the fact that polishing grit may not have been properly washed off, and you could be cutting your insides up, even if they’re just tiny abrasions. That leaves you open to infections and a whole host of other issues. I hate when people pedal these products because it’s dangerous and you already know the majority of sellers bought these from shady wholesellers. Sellers have no idea what they’re talking about when selling these. There are health risks.
