Primary

Support vessel elasticity and circulation

Quercetin glycosides have been watched in trials against blood pressure and platelet aggregation. People with heavy legs from sitting more often notice lighter legs and extremity temperature after several continuous weeks. Quercetin is denser in yellow-skinned types, and circulatory sensation is clearer too.

Help respiratory mucosal comfort

Sulphur volatiles are traditionally used in warming dishes at the start of a wind-cold. People who get a runny nose and itchy throat at season change more often notice mucosal comfort after several continuous days. Volatile sulphides act relatively briefly; mucosal comfort is mostly in-season. This onion path is easier to match with everyday sensations after several continuous days to weeks.
