Synephrine HCl is an alkaloid extract of bitter orange (Citrus x aurantium L.) peels. Synephrine is similar structurally to ephedrine, and like ephedrine it acts as an adrenergic (adrenaline-like) stimulant. Even so, synephrine is not as potent as ephedrine and is found, at least by some studies, to be much less active in the central nervous system. Further synephrine has not been demonstrated to produce (at least in oral doses) the severe side-effects and toxicity of ephedrine. Synephrine still appears to act upon most adrenergic receptors, including the alpha-1 receptors which can constrict blood vessels causing increased blood pressure, and to a lesser degree the beta receptors, which can increase heart rate and contractility. It appears that synephrine' primary action, though, is through activation of the beta-3 adrenergic receptors that are found on fat cells, thus promoting weight loss by breakdown of fat. Synephrine also should not be confused with neosynephrine (phenylephrine), a drug often used as a nasal decongestant.
From what I understand, Hoodia (as used by the people who used it originally) was something they chewed on (the leaves). It's got much less (if any) effect when orally ingested...that's why you see all the hoodia chewing gums and shit.
the best thing she has found that works is drinking a cup of hot greetea when she is hungry it makes her hunger goaway and help with the metabolic process.
