An Apparent Relation of Nightshades (Solanaceae) to Arthritis
Diet appears to be a factor in the etiology of arthritis based on surveys of over 1400 volunteers during a 20-year period. Plants in the drug family, Solanaceae (nightshades) are an important causative factor in arthritis in sensitive people. This family includes potato (Solanum tuberosum L.), tomato (Lycopersicon esculentum L.), eggplant (Solanum melongena L.), tobacco (Nicotiana tabacum L.), and peppers (Capsicum sp.) of all kinds except the black pepper (family, Piperaceae). A buildup of cholinesterase inhibiting glycoalkaloids and steroids from consumption and/or use (tobacco) of the nightshades and from other sources such as caffeine and some pesticides (organophosphates and carbamates) may cause inflammation, muscle spasms, pain, and stiffness. Osteoarthritis appears to be a result of long-term consumption and/or use of the Solanaceae which contain naturally the active metabolite, vitamin D3, which in excess causes crippling and early disability (as seen in livestock). Rigid omission of Solanaceae, with other minor diet adjustments, has resulted in positive to marked improvement in arthritis and general health.
