Boldo Leaf (Peumus boldus): Boldine Isoquinoline Alkaloid, Gallbladder Contraction, and Hepatic Bile Fluidity

The Premier Digestive Shrub of the Chilean Andes

Native to the Mediterranean-like coastal scrublands of central Chile, the aromatic evergreen shrub Boldo (Peumus boldus) produces thick, leathery leaves with a pungent camphoraceous aroma that has formed Latin America\'s primary hepatic and gallbladder remedy for centuries.

1. The Choleretic Alkaloid: Boldine

The primary therapeutic molecule in Boldo leaves is the aporphine alkaloid Boldine:

• Choleretic & Cholagogue Action: Directly stimulates hepatocytes to increase bile fluid volume and promotes smooth gallbladder contraction, assisting the enzymatic breakdown of rich dietary fats.


• Hepatocellular Antioxidant Protection: Scavenges free radicals in liver microsomal membranes during metabolic detoxification.

2. Responsible Infusion Guidelines

Due to high active alkaloid density, Boldo tea is best prepared with 1 gram of dried leaves per cup, consumed for 7 to 14 consecutive days after heavy meals rather than year-round.
