Its interesting to hear so many people say the arnica is good.
I tried SBC once - think it must have been a TSV - and it was truly awful. I remember a huge bottle if the pink gunk (collagen?) that did absolutely nothing other than my skin feel awful, and the propolis one that i thought might help my young daughter’s sensitive eczema prone skin. When she put a bit on to try it it stung so much she ended up in tears and we had to wash it off straight away. It all went in the bin as I recall. Ive never been tempted since.
