Lupinus

Also known as White lupin, Field lupin, Egyptian lupin.

CoolingDryingTaste: Bitter

Lupinus is a large genus of the pea family, with white lupin the species most often gathered for medicinal and food use across the Mediterranean and Middle East. The seed is the part used, and it has a long history both as a debittered nutritive food and, in smaller and carefully prepared amounts, as a bitter tonic and folk remedy in eclectic and European traditional medicine. Wild and undomesticated lupin seeds are bitter and contain quinolizidine alkaloids that must be reduced by prolonged soaking, leaching, or selective breeding of sweet varieties before the seed is safe to take internally in any quantity.

Indications what the tradition reached for it in

Specific indications

Poor appetite with a sluggish, bitter-deficient digestion, where a small dose of the bitter seed is used before meals to rouse the stomach.

Traditional folk use of the ground seed as an adjunct for mild blood sugar elevation in a patient otherwise following dietary measures.

Safety

Low dose botanical. Used in drop doses in the classical practice; not a plant to dose freely.

Pregnancy: Avoid internal use beyond ordinary dietary amounts, since traditional emmenagogue use and the alkaloid content of poorly processed seed both argue for caution.

Breastfeeding: Avoid internal medicinal use beyond ordinary dietary amounts due to insufficient safety data and alkaloid content in inadequately debittered seed.
