sedative hypnotic effect

Lavender essential oil is mainly used in aromatherapy or massage. Abroad, in 1993, Tullamore in Ireland mixed volatile oils extracted from rosin, juniper, lavender and sweet oregano at Genoral Hospital to improve the sleep of the elderly. In 1995, Graham also tried this, aiming to reduce patients' sleep disturbance and help them fall asleep quickly. After 2 weeks of combined use with volatile oil atomization treatment, the number of patients who reported having a good night's sleep increased significantly, and the number of patients who reported that they needed a particularly quiet environment when sleeping at night decreased significantly. In Xinjiang, many Uyghur hospitals use lavender whole plant preparations to treat neurasthenia and insomnia.

Antispasmodic effect

In addition to its effects on the central nervous system, animal experiments have shown that lavender essential oil also has an antispasmodic effect on the smooth muscles of the ileum and uterus. Its antispasmodic effect acts neither through adrenergic and cholinergic receptors nor through calcium ion channels, but by increasing intracellular levels of cyclic adenosine monophosphate. Lavender essential oil also has some applications in obstetrics. For example, adding it to bath water can reduce the pain and discomfort of mothers after childbirth.

Antibacterial effect

Lis-Balchin discovered that lavender essential oil has activity against a variety of bacteria.

Linalool is the main antibacterial component of lavender essential oil. It can inhibit the growth of 17 types of bacteria (including Gram-positive bacteria and Gram-negative bacteria) and 10 types of fungi. Both lavender essential oil and essential oil vapor have been shown to have some antifungal activity. 1% and 10% lavender extract can inhibit the conidial germination and spore growth of Botrytis cinerea, and the inhibitory effect on spore growth is more effective than that on mycelium. Lavender essential oil vapor can also inhibit the growth of dead bacteria of Aspergillus fumigatus. The dosage required is equivalent to that of tea tree oil, but higher than that of lemongrass oil, cinnamon oil and thyme oil. The effective concentration of lavender essential oil against Trichophytonmentagrophytes and T. rubrum is 10~20Lg/ml. At a concentration of 150Lg/ml, it can kill 60 kinds of conidia.

Neuroprotective effect

Lavandula angustifolia flower aqueous extract dose-dependently inhibits glutamate-induced neurotoxicity. Extracts at 100Lg/ml and 1mg/ml significantly blocked glutamate-induced neurotoxicity in rat cerebellar granule cells cultured in vitro, with the most effective dose being 1mg/ml.

lipid-lowering effect

Some scholars cut human adipose tissue into small pieces and cultured them in 0.05% collagenase solution, and added the extract to the culture tube. Fat degradation rate: The tube with lavender extract added is (1.12+0.10) mg fat/culture tube, the tube with lavender and fennel extract is (2.37+0.18) mg fat/tube, the control tube without extract is (0.35+0.09) mg fat/tube.

Treat cardiovascular insufficiency

Some people use several herbal infusions containing lavender to treat cardiovascular insufficiency. The liquid reduces headaches, dizziness, blood cholesterol levels and symptoms of low arterial pressure.

Treat neurosis

Li Shusheng et al. used the scent of lavender flowers to treat 50 cases of neurotic patients. One course of treatment was 8 weeks. They found that neurotic sleep disorders, mood disorders, somatization symptoms SCL-90 (Symptom Self-rating Inventory), STAI (State and Personality Anxiety) Self-examination scale), EEG (electroencephalogram), and REG (cerebral blood flow diagram) were all improved, and no adverse reactions were seen.
