Cardamom is involved in treating Alzheimer’s disease with the following mechanisms: anti-cholinesterase activity, induction of endogenous antioxidants such as glutathione and superoxide dismutase, impeding the production of reactive hydroxyl radicals, preventing the formation of Aβ42 deposits, and protecting cells from iron-induced death. Here, BCHE is linked to early-onset autosomal dominant Alzheimer disease.
