Friend, I'm a fan of natural remedies that I trust widely. But it is good to know that if the emotional part that the disease causes in the physical body is not healed, I do not want to lower your spirits but as a holistic therapist that I am I will tell you that arthritis is caused by mental rigidity, you are not asking me But I suggest that in addition to turmeric and ginger you could complement your physical situation by taking the Bach Flowers, since they are going to work your mental and emotional part regarding your rigidity and I assure you so that you can improve completely.
If you have not yet heard about the bach flowers, I send you the link of the photograph.
