NIGHTSHADES

Nightshades are plants belonging to the Solanaceae species.  

Nightshade sensitivity is a non-immune adverse reaction to alkaloids—like solanine, capsaicin, and nicotine—found in plants of the Solanaceae family.

Adverse reaction to Nightshades can result in symptoms such as welts on the skin, rashes, nausea, diarrhoea, dizziness, inflammation, joint stiffness, migraines and fatigue. 

Nightshade sensitivity may also contribute to symptoms of arthritis and painful swelling of joints.

Symptoms can arise 30 minutes to 48 hours after consumption giving non-immune, delayed reaction often related to the body's inability to break down the alkaloids, leading to digestive issues and inflammation & symptoms.
