I found Collagen useless and Propolis as you mentioned amn, I have used other SBC items as well but still stick by Arnica, even other peoples arnica gel is not a patch on SBC.
'thermal rub'The wintergreen is amazing if you have never tried it. I can’t wait for this
I've never bought any SBC products, however, I have great faith in homeopathic remedies, took arnica tablets after twisting my ankle quite badly & use Neal's Yard Arnica Salve whenever I have aching muscles or have done something daft that may cause a bruise. My favourite product for really bad sprains is NY's Warming Salve, it contains turmeric & my Mr T says that it smells like stale cigarettes but it's very effective.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.
