Alzheimer’s disease (AD) is the most common type of dementia that leads to increasing death and mental disability
among humans. Current therapy of AD mainly relies on the use of acetylcholinesterase inhibitors (AChEIs) or antagonists
of N-methyl-D-aspartate receptors (NMDARs), which only relieve the symptoms of the disease but not halt its progression.
Nevertheless, Traditional Chinese medicines (TCM) are highly prized as many bioactive components isolated from TCM are
beneficial for treating AD. In this review, we summarize the latest information on TCM and the bioactive components according
to their mechanistic role in alleviating AD. They act as modulators of α- and β-secretases, and inhibitors of betaamyloid
(Aβ) aggregation. Some of them suppress Aβ-induced neuronal cytotoxicity and inflammation. Hence, this work has
demonstrated the feasibility of applying TCM in AD therapy and the possibility of screening of constituents in TCM in the
