I don't know anything about ganglions, but I'm taking high strength turmeric to help with knee and shoulder pain, which it has got rid of after about 6 weeks. 🙂 I realised that the slight stiffness in my finger joints has gone too. I bought Nature's Best 20,000mg turmeric tablets. I only buy my supplements from them because they guarantee purity and potency. Many brands don't contain the quantity the label says, and can be made in China and packaged here, and legally sold as made in Britain. 🙄 Turmeric is anti inflammatory, and as inflammation is the cause of many/most chronic health problems, I intend to take it long term. It's been one of the most beneficial things I've taken.
