Earlier, the same research group had reported a normal human blood plasma level of synephrine of 0.90 13.69 ng / mL.

Furthermore, the marked brocho-constriction produced by injections of histamine was not reversed by either l-synephrine or d, l-synephrine.

The potency of synephrine at adrenergic receptors of the ?-class ( regardless of sub-type ) is much lower than at ?-receptors.

One current reference source describes synephrine as a vasoconstrictor that has been given to hypotensive patients, orally or by injection, in doses of 20 100 mg.
16.
Racemic synephrine, given intramuscularly, or by instillation, was found to significantly reduce the inflammation caused by instillation of mustard oil into the eyes of rabbits.

The ingredient drawing the most attention is bitter orange, which McClellan says the FDA is monitoring closely because it contains synephrine, a stimulant chemically similar to ephedra.
18.
However, the potency of synephrine at these receptors is relatively low ( i . e . relatively large concentrations of the drug are required to activate them ).
19.
Trace levels ( 0.003 % ) of synephrine have also been detected in the dried leaves of " Pogostemon cablin " ( patchouli, Lamiaceae ).
20.
There is some evidence that synephrine also has weak activity at 5-HT receptors, and that it interacts with TAAR1 ( trace amine-associated receptor 1 ).
