What Are Nightshade Vegetables?

Nightshades are members of the Solanaceae family (tomatoes, peppers, eggplants). They include bell peppers, eggplant, cabbage and cauliflower. All these plants contain chemicals called terpenes which have been used medicinally for centuries. However, it was not until the 1970’s when scientists discovered that some of these compounds had anti-inflammatory properties. These compounds were named “cannabinoids” because they are found in marijuana.

The most well known cannabinoid is THC or tetrahydrocannabinol, which produces its effects by interacting with the CB1 receptor. Other cannabinoids such as CBD and CBC act through different receptors but all of them interact with the same receptor system.

The endocannibinoid system plays a role in many physiological processes including pain perception, appetite regulation, immune function and even memory formation.

CBD (cannabidiol) is another cannabinoid that has been shown to have anti-inflammatory effects. It acts mainly at the CB2 receptor.

Cannabinoids may also exert their anti-inflammatory actions through other mechanisms such as inhibition of prostaglandins, nitric oxide production and activation of nuclear factor kappa B (NFkB).

How Does Inflammation Affect Joint Health?

The two most common inflammatory arthritic conditions are rheumatoid arthritis and osteoarthritis.

Rheumatoid arthritis is an autoimmune disease that causes the immune system to wrongly identify the lining of the joints as harmful, and then attacks it, resulting in inflammation of the joints. The affected joints become swollen, painful and stiff and movement becomes difficult.

Rheumatoid Arthritis can also affect other organs of the body.

Osteoarthritis is the “wear and tear” of the joints that occurs as a consequence of normal use. Cartilage protects the ends of bones where they meet.

In Osteoarthritis this protective layer starts to break down, causing pain, tenderness and loss of mobility.
