About EGCG
Plant: Epigallocatechin gallate, from Camellia sinensis (green tea)
The most active catechin in green tea. A powerful antioxidant with neuroprotective benefits that also raises regulatory T-cell counts, helping calm autoimmune-type overreaction — a component of Bartonella's basic protocol package.
