Chemical components:
The main active ingredient is Tianma Gan, also known as gastrodin, of about 0.3 percent or more are Tianma ether gastrodioside, p methanol p-hydroxybenzyl alcohol,p-hydrooxybenzyl aldehyde, vanillyl alcohol, daucosterol, succinic acid, citric acid and methyl ester, palmitic acid, β-sitosterol, Tianma polysaccharide, sugar, a variety of amino acids and trace elements, such as.

Tianma artificial cultivation compared with wild Tianma, the main ingredient is contained in the agreement, but Tianma by HPLC, artificial cultivation of wild than the high of about 100. Gastrodin is now able to synthetic.

Pharmacological effects:
1. Sedation analgesia
Tianma the sedative, analgesic effect may be peripheral to the central nervous system and its suppression DA, NA the re-uptake and storage, thus reducing the brain related to the DA and NA.
"Compendium of Materia Medica" Tianma records of "multi-language trance, good panic missing forgotten." "What's biological" Tianma有镇静作用records, governance neurasthenia. Tianma has a large number of the reported analgesic effect.

2. Anticonvulsant, antiepileptic
China's utilization of anti-panic Tianma has a long history of anti-epileptic, the medical records already. Ming Li Shizhen book "Compendium of Materia Medica" record: Tianma "all the main rheumatoid Bi, Juluan limbs, children with epilepsy panic wind gas." Since the 1950s, many scholars through animal experiments, affirmed the Tianma and its active ingredients Tianma -, Alcohol-and-a-a-aldehyde with anti-panic, all anti-epileptic effect.

3. Anti-motion sickness
Rotating mice significantly increased the food intake, increased rotation mice in the maze of spatial ability, suggesting that Tianma alcohol extract can improve the rotation induced movement symptoms.

4. To improve learning and memory
Tianma the brain can significantly promote the proliferation of glial cells, showed increased number of glial cells, cells of the area increased. Glial cells of the brain more active neurons, enhance learning and memory play a support role.

5. The protection of nerve cells
Gastrodin on cultured nerve cells in ischemic reperfusion a protective effect. Gastrodin could antagonize the excitatory amino acid neurotoxicity.

6．The role of the heart
Tianma a protective effect on heart, can affect Pituitrin on rat myocardial ischemia caused by changes in the electrocardiogram, can also increase coronary flow.

7. Blood pressure of the blood vessels
The results showed that: Tianma can lower blood pressure, can reduce blood vessels in the serum lipid peroxide (LPO), with anti-lipid peroxidation to achieve the anti-aging and heart and vascular disease prevention purposes. The mechanism may be related to the chemical constituents in the Tianma is rich in zinc, copper, selenium, chromium, manganese, and other trace elements related.

8. Anti-fatigue
Tianma have enhanced endurance, the role of anti-fatigue.

9.Anti-inflammatory
Tianma experiment proved that oozed from a variety of inflammation and swelling are inhibited. Repeated use, can significantly increase the Tianma the weight of the spleen, suggesting that immune function may Tianma on a facilitating role.

10.To promote immunization
Tianma and promote polysaccharides Tianma body specificity and the role of non-specific immunity.

11.Anti-role
Bai Xiuzhen will be equivalent to 1996 capsules made of Tianma, taking to the elderly, three months after the serum of hydroxyproline (HOP) content, by clinical observation, found significantly higher levels of serum HOP that Tianma have anti-aging effects. This may Tianma and trace elements in zinc, copper, selenium, chromium, germanium, and other content.

12.Anti-radiation effects
The results show that the exclusion Tianma cytotoxicity, and then show a certain procedure of anti-radiation effect.

Clinical applications:（《Modern medicine and clinical pharmacology》）
1.Neurasthenia
Gastrodin injection in the treatment of brain trauma syndrome have a certain effect.

2.Of vertigo
Gastrodin injection used in the treatment of vertigo syndrome effective rate was 92.2 percent. Mernier of disease, drug-induced vertigo, vertebral artery insufficiency, such as the effective rate was 95.5 percent.

3.Hemifacial spasm
The total effect of the recent efficiency of 60 percent or more, especially the onset of middle age, muscle cramps, mouth to good effect.

4.Neuralgia
Artificial cultivation of a variety of Tianma neuralgia, synthetic Tianma in the treatment of vessels and nerves are certain effects of a headache.

5.Hyperlipidemia
Hypercholesterolemia on the effective rate was 82.6 percent, to Hypertriglyceridemia the effective rate was 75 percent, patients dizziness, flustered, and other symptoms has also improved.
