Part Used: fruit (immature) History:
Citrus aurantium L, belonging to the family Rutaceae, is widely
distributed in China. Zhishi, the Chinese traditional name for
Citrus aurantium, has long been a folk medicine in traditional
Chinese medicine (TCM)to improve indigestion and help stimulate the
Qi (energy force). It also has been a folk remedy in Italy since
the 16th century for fevers like malaria and as an antiseptic.
Recent studies have confirmed that Zhishi, replacing Ma Huang, can
be used for treatment of obesity without the negative
cardiovascular side effects.Function:
Synepherine is the main active compound found in the fruit of
Citrus aurantium, which is effective in providing the energy boost
(caloric expenditure), aiding the expulsion of wind, warming the
stomach, improving the appetite, and increasing metabolic rate.
Citrus aurantium is theorized to stimulate fat metabolism without
the negative cardiovascular side effects experienced by some people
using Ma Huang. It is also a mild aromatic expectorant, a nervine
and a laxation for constipation.1. Weight Loss
The most likely explanation for weight loss effects attributed to
citrus aurantium supplements is the amphetamine-like effects of the
alkaloids. Although this effect is likely to be somewhat less
dramatic than effects induced by Ma Huang (ephedra alkaloids),
users can expect variable effects including enhanced caloric
expenditure, reduced appetite and heightened feelings of energy,
all of which are likely to result in weight loss. [1],
[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12] A recent study
conducted in dogs also suggests that synephrine can increase
metabolic rate in a specific type of fat tissue known as Brown
Adipose Tissue (BAT).
Since synephrine and several other compounds found in zhi shi are
structurally similar to ephedrine and act as stimulants to specific
adrenergic receptors (beta-3, but not beta-1, beta-2 or alpha-1),
zhi shi does not appear to have the same negative central nervous
effects of Ma Huang (ephedra), which stimulates all beta-adrenergic
receptors.2. Mild Exhilarant
Studies have attributed the energy enhancing effect of synephrine
to stimulation of the Centre Nervous System [12], [14]. This
integrated effect may include increased circulation of blood
through the heart and cerebral tissue [5], elevated blood pressure
and improved mental activity, which would readily qualify
synephrine as a mild exhilarant.3, Digestive Tract Discomfort
Conformed with traditional use, Citrus Seed Extract can stimulate
the digestive tract by stimulating stomach functions as well as
having laxative and gas-relieving actions [8, 13] It may also help
relieve nausea and sooth stomach disturbances such as gas and
bloating [4]4, Anti-Microbial Activities
Citrus Seed Extract is a non-toxic and organic anti-microbial
product. It shows a bacteria growth inhibitory effect in vitro [11]
and can also inhibit the infection capability of some viruses. [9]
Thus the extract is wildly used as a sanitizing disinfecting agent,
as a preservative in foods or cosmetics, and in agriculture as a
fungicide, anti-bacterial, anti-parasitic and anti-viral
agent.Dosage
Standardized synephrine as Citrus Aurantium fruit extract is
recommended. A dose of 4-20 mg of synephrine per day is a typical
dose found in products providing 200-600 mg of a standardized
citrus aurantium extract (3-6% synephrine). [3]Safety
Both isolated synephrine and citrus aurantium extract have been
shown to raise blood pressure in animal studies. Until more studies
are conducted on the safety, pharmacology and efficacy of citrus
aurantium as a thermogenic supplement, it should be treated as an
ingredient with mild stimulant properties and should be avoided by
individuals with cardiovascular concerns such as high blood
pressure or heart problems [3, 4, 5, 8] No toxicity is reported by
oral ingestion. Handled at full strength, avoid contact with eyes
or breathing the vapor
