What Nutritional Value Does Peppermint Oil Have
The main component of peppermint oil is levo-menthol, the content is 62.3%-87.2%, and it also contains levo-menthone, isomenthone, pulegone, decyl acetate, methyl menthyl acetate, methyl benzoate, α- and β-pinene, β-thujene, 3-pentanol, 2-hexanol, 3-octanol, dextro-myrcene, limonene and eucalyptol, α-terpineol, etc.
Its nutritional value includes:
- Choleretic effect: can significantly increase the amount of bile secretion, with obvious choleretic effect. Chen Guangliang and others fed peppermint oil through the duodenum of rats, and the effect of promoting bile secretion was most obvious for 1 to 2 hours. Compared with before administration, the excretion of bile acids in bile slightly increased, the content of cholesterol decreased, and the content of bile pigments did not change significantly, indicating that peppermint oil has an obvious choleretic effect and can increase the excretion of bile acids in bile.
- The effect of dissolving stones and expelling stones: it can reduce the concentration of cholesterol, which is beneficial to the prevention and treatment of cholesterol stones. Leuschner and other experiments found that menthol can effectively improve the efficiency of complete dissolution of 10~12mm gallstones (increase by 15%).
- Anti-inflammatory and analgesic effect: The opioid effect of L-menthol (ie menthol) on the central nervous system can make the pain disappear. Further studies have shown that menthol can achieve analgesic and sedative effects by modulating gamma-aminobutyric acid (GABA) and glycine receptors in the mammalian nervous system. Menthol is a stereoselective modulator of this inhibitory ion channel. Therefore, peppermint oil has considerable anti-inflammatory and analgesic effects.
- Antispasmodic effect: Peppermint oil can inhibit the contraction activity of the isolated ileum of guinea pigs, reduce its contraction amplitude, frequency and tension, and can antagonize intestinal spasm caused by histamine or acetylcholine in a concentration-dependent manner. Studies have shown that this inhibitory effect is non-specific, and its mechanism of action is likely to inhibit the activity of guanylate cyclase so that GTP cannot be converted into cGMP. Protein kinases are difficult to activate, thereby inhibiting or relaxing intestinal muscles.
- Anti-infection effect: 14 kinds of common bacteria were selected for testing, and it was proved that menthol has different degrees of antibacterial effect on various fungi and bacteria, and Staphylococcus epidermidis and Bacillus subtilis are more sensitive to it.
