Ok guys, I found foodgrade hydrochloric acid, hydrochloric acid or muriatic acid is being used as a drug in homeopathy.

Its used in very rare events though and its rare to find. I made a search for muriaticum acidum liquid, and I found that this guy from U.K. carries it:

I asked him a few questions about the product for use in homeopathy, (purity and concentration) and I am waiting for a response. This product though is more expensive than using hydrochloric acid.

In any case I bought pure(?) hydrochloric acid 37% and I was wondering what is the easiest way to dilute it (glass bowl, water and a syringe?)

So this is a 2% HCL solution? If we start with 37% HCL it would be 1 part HCL to 18.5 parts water right?

Do HCL and water emulsify well?
