Anise may have potential and substantial relaxant effects in reduced overexpression of vessel and muscle constrictions in the precipitation of pain, some scientists suggested.
Anise is a flowering plant of the species of Pimpinella anisum, genus Pimpinella, belongings to the family Apiaceae native to Egypt and the Mediterranean region, used in traditional herbal medicine as a fragrance in soaps, oils, and mouth fresheners and stomachic, antiseptic, anti-spasmodic,...
Chemical constituents
Anethole, D-pinene, I-phellandrene, Alpha-terpineol, Safrol, Methyl chavicol, Resin, Shikimic acid, etc.
According to the evaluation of Anise 3 hydroalcoholic extracts claimed to have a substantial effect in tracheal and ileal smooth muscles in 3 different concentrations of doses at 40% (HA(40%)), 60% (HA(60%)) or 80% (HA(80%)) researchers found that
* Application of all extracts at half maximum effect,50 microg/mL EC(50) inhibited acetylcholine-induced contraction.
* However, the extract HA(60%) at 5-50 microg/mL(EC(5-50)) concentration-dependently relaxed acetylcholine-pre-contracted tissues and HA(40%) and HA(80%) did not exert relaxant action in any volume out of indicated range.
These results suggested that the substantial effect in tracheal and ileal smooth muscles of Anise was associated with a dose-dependent manner.
In other words, only certain concentrations of Anise hydroalcoholic extract are effective in reduced muscles and vessels constriction in the induction of pain.
Injection of muscle constriction substances such as N(G)-nitro-L-arginine methyl ester (L-NAME, 100 microM), 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, 3 microM) and oxyhemoglobin (10 microM) were also inhibited by HA(60%) in doses concentration-dependent manner through the influence of muscle relaxation.
This inhibition suggested that Anise not only ameliorates the tracheal and ileal smooth muscle pain caused by natural spasmodic activities but also pain caused by the injection of muscle and vessel contraction substances.
Moreover, an additional treatment of nitric oxide synthase(L-NAME) in induced production of vascular smooth muscle cells and enhanced the maximal contraction induced by acetylcholine, administration of HA(60%) expressed a strong activity in modulated NO contractile response, stimulated by primary transmitter released by inhibitory nerves through cyclic GMP-dependent which is found to have an implication in the regulation of smooth muscle relaxation and other independent mechanisms
Further observation also indicated that injection of HA 60% showed an insignificant effect in calcium chloride(CaCl(2))-induced muscle contraction.
Dr. Tirapelli CR, the lead author at the Escola de Enfermagem de Ribeirão Preto. said, "The relaxant action displayed by Pimpinella anisum justifies its use in folk medicine as an antispasmodic agent".
In isolated tracheal chains of the guinea pig induced by 10 microM methacholine in non-incubated tissues (group 1) and incubated tissues with 1 microM propranolol and 1 microM chlorpheniramine (group 2), to investigate the relaxant effect of Pimpinella anisum aqueous and ethanol extracts and essential oil, researchers showed that injections Anise aqueous and ethanol extracts, essential oil and theophylline, a conventional medicine used to relax bronchial smooth muscle in COPD and asthma patients display a substantial activity in exhibited relaxant effects in compared to those of controls.
There was no significant difference between both Pimpinella anisum aqueous and ethanol extracts in promoted muscle relaxation but both exerted lower efficacy in compared to those of theophylline.
Interestingly, the applications of essential oil and 10 nM atropine, a muscle relaxant medicine, used as a nerve anticholinergic agent, blocked the neurotransmitter acetylcholine in the central and the peripheral nervous system is responsible for the involuntary movement of smooth muscles and reduced the muscle contraction caused by methacholine, a substance used to tighten the lung muscle and airway for test of asthma.
These results indicated a potential activity of bronchodilatory and anticholinergic effects of essential oil, aqueous, and ethanol extracts from Anise.
However, researchers also found that application of all doses expressed insignificant effects in inhibited histamine (H(1)), smooth muscles, vascular endothelial cells, the heart, and the central nervous system or stimulated beta(2)-adrenergic receptor in binding to epinephrine.
Dr. Boskabady MH, after taking into account other co-founders, said, "....showed that the relaxant effect of this plant is not due to an inhibitory effect of histamine (H(1)) or stimulatory effect of beta(2)-adrenergic receptors, but due to inhibitory effects on muscarinic receptors".
Collectively, the efficacy of Anise in elevated muscle and blood vessel pain was associated with a number of mechanisms, not invoked by the constriction caused by allergens or stimulants.
Taken together, Anise aqueous and ethanol extracts and essential oil may be used as adjunct herbal medicine in reducing the risk of diseases associated with spasmodic muscle contraction in the induction of muscle cramps accompanied by a sudden burst of pain caused by abnormal nerve stimulation or by abnormal activity of the muscles and vessels.
