I’ve been using BSO for several weeks. I started using it for my serious knee pain and it’s amazing! Works really fast, I rub it on my knee and within a minute or two, no more pain. It’s not like pain creams that have a strong cold or burning sensation and there’s no smell after a few minutes. I was told that if you have sensitive skin to put a carrier oil with it, but so far, I’ve just used it straight and haven’t had any skin problems. Black Seed Oil can be used topically all over your body for pain or added benefit, soft skin. I’ve also been using it on my nails and cuticles for the ridges that have developed, just started that so don’t have any results yet. Taking internally I put it in my Golden Milk (turmeric, ginger, hot milk) at night.
