The Kamsa Indians prepare a decoction of this plant which is 
taken as a gargle to relieve chest and throat pains. 
It is perhaps significant that the leaves of another species of this 
genus, the Amazonian Oxalis Martiana Zucc., are used in Brazil 
in the form of a gargle to relieve pains of angina (LeCointe: A 
Amazonia Brasileira 3 (1934) 108). 
Leucoanthocyanines have been reported from some species of 
Oxalis (Bate-Smith, E. C.: Journ. Linn. Soc. London (Botany) 58 
(1962) 95-173).
