Description

The core effects of Gastrodia elata are calming wind and relieving spasms, suppressing liver yang, and dispelling wind and unblocking meridians. It is widely used to treat dizziness, headaches, numbness of limbs, and convulsions. Modern research also shows that Gastrodia elata has the effects of improving cerebral circulation, calming the nerves, protecting nerve cells, and assisting in immune regulation.

1. Calming Wind and Relieving Spasms: Gastrodia elata can calm liver wind and relieve spasms, and is suitable for convulsions, infantile convulsions, tetanus, and other conditions caused by internal liver wind. Its active ingredient, gastrodin, can inhibit excessive excitation of the central nervous system and reduce the risk of abnormal discharges. It is often used in combination with Uncaria rhynchophylla and scorpion, such as in Gastrodia elata and Uncaria rhynchophylla granules.

2. Suppressing Liver Yang: It has a significant effect on improving symptoms such as dizziness, headaches, tinnitus, and flushed face and red eyes caused by liver yang hyperactivity, and is especially suitable for those under long-term stress and emotional fluctuations. Clinically, it is often used to treat dizziness caused by hypertension, migraines, and Meniere’s disease, often in combination with abalone shell and Achyranthes bidentata. 3. **Dispelling Wind and Unblocking Meridians:** It can dispel wind and unblock meridians, relieving rheumatic pain, limited joint flexion and extension, and numbness or hemiplegia caused by stroke sequelae. By improving local blood circulation and reducing inflammation, it is often used in combination with Notopterygium incisum, Angelica pubescens, and Angelica sinensis.

4.Sedative and Cognitive Improvement:** Gastrodia elata has a central sedative effect, prolonging sleep time and relieving anxiety and insomnia. It is suitable for neurasthenia, menopausal syndrome, and other conditions causing frequent awakenings and vivid dreams. Simultaneously, Gastrodia elata polysaccharides and gastrodin can promote cerebral blood flow and enhance memory, showing potential as an adjunct treatment for mild cognitive impairment and Alzheimer’s disease.

5. Cardiovascular and Cerebrovascular Protection:** Modern pharmacology has confirmed that Gastrodia elata can dilate cerebral blood vessels, increase cerebral blood supply, mildly lower blood pressure, and has a certain protective effect against myocardial ischemia, helping to prevent stroke and cardiovascular events.
