So I’ve learnt a new word today: galactagogue, a substance that induces lactation. I came across it in the title of a paper ((Steve Froemming. Traditional use of the Andean flicker (Colaptes rupicola) as a galactagogue in the Peruvian Andes. Journal of Ethnobiology and Ethnomedicine 2006, 2:23)) in the Journal of Ethnobiology and Ethnomedicine, which seems to be admirably open access. The substance in question is the dried carcass of a bird called the Andean Flicker:
The bird’s use as a galactagogue appears to be motivated by both metaphorical associations and its perceived efficacy, and conceptually blends human and animal healthcare domains.
It’s really fascinating stuff. The paper has a list of Andean galactagogues, which includes many preparations derived from crops. Various wild plants and herbs are also used in this way in Europe, and some of the Andean remedies are likely to have been introduced in the 16th century, while others are native to the region. The flicker seems to be a pre-Colombian practice.
