Sulfur technical quality usable?

Sulfur exists as a raw material on the Belgian market only as a technical quality. Theoretically, such a product may not be used in a preparation. The qualities on the market have not undergone any analysis (in accordance with pharmaceutical standards).

However, given the lack of any pharmaceutical quality, a risk assessment must be made for certain patients so that they can nevertheless be helped. It goes without saying that in that case there is only external use.
