Rating (out of 5): 2

Cacao has a long history of traditional use, particularly among indigenous cultures of Central and South America, where it was consumed as a beverage for its stimulating and invigorating effects. Traditionally, cacao has been regarded as a heart and mood tonic, and its stimulating properties—largely due to its theobromine and low caffeine content—were thought to "awaken" the body and mind. These effects are indirectly related to the sympathetic nervous system, as stimulants can increase alertness and arousal, which are sympathetic responses.

However, while modern research has explored cacao’s impact on cardiovascular health, cognition, and mood, direct scientific evidence linking cacao consumption to targeted support of the sympathetic nervous system is limited. Most studies focus on cacao’s polyphenols, theobromine, and their effects on blood flow, mood, and neurochemistry rather than direct modulation of sympathetic nervous activity. Thus, the use of cacao for "supporting the sympathetic nervous system" is primarily justified by its traditional reputation as a stimulant rather than strong scientific validation.

In summary, cacao’s use for supporting the sympathetic nervous system is based on traditional stimulant effects, with only modest supporting evidence from modern science regarding its general stimulating properties.
