I've heard that there is a new herb that can help with arthritis. Can you tell me more about it?

Sure, I'll do my best!  Arthritis is a condition where the joints become inflamed and painful due to inflammation in the joint lining. It's caused by a variety of factors including genetics, age, injury, and certain diseases. The most common form of arthritis is osteoarthritis (OA). There are several types of OA, but the most common is called primary OA. This type is caused by wear and tear on the cartilage in the joints. Symptoms include pain, stiffness, swelling, and loss of function. Treatment for primary OA usually involves lifestyle changes such as exercise and weight management, as well as medications like NSAIDs. Other forms of arthritis include rheumatoid arthritis and psoriatic arthritis.
