8 Sexual flavors and attributesPungent, warm, slightly toxic [1]. It enters the spleen, stomach and kidney meridians [1].
9 Functions and IndicationsIt is used to warm the middle Jiao, move qi, eliminate food and fix the large intestine [1]. Indications: cold spleen and stomach, distension and pain in the epigastrium, loss of appetite, cholera, vomiting, prolonged diarrhea, prolonged dysentery [1].
10 Usage and dosage of nutmegDecoction: 3-9g [1].
11 UsageThe aril of nutmeg is called nutmeg coat, which can be used as an aromatic stomachic agent [1].
12 Chemical compositionThe seeds contain volatile oils, the main aroma hinokiene, icariene, eugenol, methyl eugenol, pinene [1]. It also contains toxic substances myristyl ether, dihydroxytrimethoxy 8O4'neolignan, 2 (4 allyl 2,6 dimethoxyphenyl) 1,4 dihydroxy 3methoxyphenylpropan1ol, ligustral B, etc [1].
13 Pharmacological effectsThe volatile oil and its components have central inhibitory effects [1]. It is also anti-tumor and anti-inflammatory [1]. The volatile oil has a local *** on the gastrointestinal tract, while showing an expectorant effect [1]. Excessive doses given to cats can cause a semi-comatose state and death within 24 hours due to liver damage [1]. Myristyl ether has hallucinogenic effects in normal humans [1]. Methylisoeugenol has sedative, hypnotic and antibacterial effects [1]. Myristic oil is also a powerful monoamine oxidase inhibitor [1].
14 Nutmeg PoisoningNutmeg is also known as nutmeg, nutmeg, yucca, caraway berry, spleen an ruiqi, doukou, top meat, and long-shelled yucca [3]. Long shell jade fruit: also known as long-shaped nutmeg [3]. It is the skinned fruit of the same genus Nutmeg long form [3]. It is the seed kernel of Myristica fragrans, family Myrtaceae, which contains volatile oil [3]. The oil mainly contains pinene, camphene, hinokiene, eugenol, safrole and myristyl ether [3]. It has the effect of warming the middle and strengthening the stomach, lowering the qi and eliminating food, astringent and stopping diarrhea [3]. It is mainly produced in Indonesia [3]. Weak aroma, spicy flavor [3].
Myristic nutmeg is toxic in raw form, and the volatile oil has a *** effect on the gastrointestinal tract and general anesthesia [3].
14.1 Mechanisms of adverse reactionsThe drug is toxic in raw form, and nutmeg is a toxic component [3]. Pharmacological experiments show that the active effect of nutmeg is mainly myristyl ether and safrole, the former has a significant effect on the central nervous system, the drug can cause poisoning when the dosage is large, cats orally lethal dose of myristyl ether is 0.5 ~ 1ml/kg [3]. Cat oral nutmeg powder 1.8g/kg, or subcutaneous injection of volatile oil 0.12ml/kg can cause semi-comatose state and hepatic damage, and died within 24h [3]. The common dosage of this drug for internal use in decoction is 3-9g [3]. The volatile oil of this product has *** effect on the gastrointestinal tract and general anesthesia [3]. It has hallucinogenic phenomenon on normal people, and teratogenicity has been reported in recent years, the latter has a paralyzing effect, and carcinogenicity has also been reported [3].
14.2 Clinical manifestationsThis product is not concocted to remove the oil or overdose can occur poisoning, the manifestations of nausea, vertigo, hallucinations, etc., the severe cases of delirium, pupil dilatation, respiratory slowing, neurological reflexes disappeared, coma and death [3]. Determination of the content of myristyl ether and safrole is more important, and it has been reported that different commodities have been determined by high performance liquid chromatography, in which the content of the two has a large difference [3].
14.3 Therapeutic pointsThe therapeutic points of myristic poisoning are: there is no specific treatment, gastric lavage, *** to eliminate poison as soon as possible after the occurrence of poisoning, and symptomatic treatment [3].

MYRISTICAE SEMEN
15.2 SourceThis product is the dried seed kernel of Myristica fragrans Houtt.
15.3 CharacterThis product is ovoid or oval, 2-3cm long, 1.5-2.5cm in diameter. The surface is gray-brown or gray-yellow, sometimes covered with white powder (lime powder). The whole body has light-colored longitudinal grooves and irregular reticulate grooves. The umbilicus is located at the broad end, with a light-colored rounded protuberance and a dark depression at the meristem. The ridges are longitudinally furrowed, connecting the two ends. The texture is firm, the section shows brownish-yellow mixed marbling, and the wide end shows dry and wrinkled embryo, rich in oil. The aroma is strong and the flavor is pungent.
15.4 Identification(1) cross-section of the product: the outer endosperm tissue, consisting of more than 10 columns of flat wrinkled cells, containing brown material, occasionally see small square crystals, staggered into the organization of the small vascular bundles, dark brown outer endosperm deep in the light yellow endosperm to form a marble-like pattern, containing most of the oil cells. The endosperm cells are thin-walled, rounded, full of starch grains, fat oil and paste powder grains, with sparse light yellow cells. The starch granules were mostly single, 10-20 μm in diameter, and a few were compound granules composed of 2-6 fractions, 25-30 μm in diameter, with obvious umbilical points. Stained with iodine solution and immediately observed with glycerol device, larger pasty powder grains were seen mixed in the numerous blue-black starch grains. Chloral hydrate device observation, visible fat oil is often a block of flaky, scaly, heating that is into oil droplets.
(2) take 2g of powder, add petroleum ether (60 ~ 90 ℃) 10ml, ultrasonic treatment for 30 minutes, filtration, take the filtrate as a test solution. Another 2g of nutmeg control herb, the same method into the control herb solution. According to the thin layer chromatography (2010 version of the Pharmacopoeia, a Appendix VI B) test, absorb the above two solutions of 5μl, were spotted on the same high-performance silica gel G prefabricated thin-layer plate, with petroleum ether (60-90 ℃) ethyl acetate (9:1) as the unfolding agent, the expansion of the cylinder pre-saturated 15 minutes, unfolding, remove, drying, sprayed with 5% vanillin sulfuric acid solution, and heated at 105 ℃ until the spot color is clear.
