Erythrina mulungu ("Mulungu") is a tree native to South America, and its bark and extracts have been traditionally used in Brazilian folk medicine for their calming and sedative effects. The use of Mulungu is primarily based on traditional practices, where it is consumed as a tea or extract to help with anxiety, insomnia, and nervous system disorders. The rationale for its use in supporting the "GABA body system" is loosely tied to its sedative properties, as GABA (gamma-aminobutyric acid) is the main inhibitory neurotransmitter in the central nervous system and is associated with reduced neural excitability and anxiolytic (anxiety-reducing) effects.

Some preliminary scientific studies, mostly in animal models, suggest that Mulungu extracts may interact with GABAergic pathways. For example, research has shown that alkaloids in Erythrina species can have central nervous system depressant activity, possibly by modulating GABAergic neurotransmission. However, robust human clinical trials are lacking. The evidence supporting Mulungu’s efficacy for supporting GABAergic function or related symptoms in humans remains limited and mostly anecdotal.

In summary, while there is traditional use for Mulungu in supporting relaxation and sleep—functions related to GABA activity—the direct scientific validation for its use specifically to support the "GABA body system" is weak and primarily based on tradition and limited preclinical data.
