Review on 🌿 MB Herbals Alum Powder 100g (3.5oz) | Granulated Potassium Alum Powder | Purified with Shodhan Process | Aids in Canker Sores | Coarse Granulated Powder by Sasha Hsiao

EDIT: I can confirm that it's 100% no alum. I went to the store and bought my regular McCormick alum (which of course I should have done first) and it made my boil burn so hard - just like it should. While it drew no attention. I don't know what the heck it is, but it's definitely not granular alum powder as advertised. How do I know? I put it on a huge cancerous growth and it didn't sting a bit. Doesn't taste or look like alum either. I have been using real alum powder to cure stomatitis for many years. Another reviewer said Tone - I agree. Buy alum elsewhere.
