Gastrodia Elata / Tian Ma

【Benefits】

In traditional Chinese medicine, Gastrodia elata (Tian Ma) is renowned for its effects of calming wind to relieve spasm, suppressing liver yang, and dispelling wind to unblock collaterals. It effectively alleviates symptoms like convulsions and tremors caused by liver wind, headache and dizziness induced by liver yang hyperactivity, and limb numbness and joint pain due to wind-damp obstruction. From a modern research perspective, it contains bioactive components such as gastrodin, gastrodia polysaccharides, and volatile oils, which have sedative, anticonvulsant, brain circulation-improving, and anti-inflammatory effects, helping to relieve neurological discomfort and protect brain function.

【Medicinal Components & Effects】

Gastrodia elata is rich in active components. Gastrodin is the key, exerting sedative, anticonvulsant, and brain-protective effects by regulating neurotransmitter release and improving cerebral blood circulation. Gastrodia polysaccharides have immunomodulatory and antioxidant properties, enhancing the body's resistance and scavenging free radicals. Volatile oils contribute to anti-inflammatory and analgesic effects, relieving joint and muscle pain. These components work together to calm wind, suppress liver yang, and maintain neurological and motor system health.

【Storage Methods】

• Store in a cool, dry, and well-ventilated place (temperature 8–15℃, humidity below 60%), away from direct sunlight and high humidity to prevent mold, insect infestation, and softening.
• Use airtight containers like glass jars or vacuum-sealed bags. For dried Tian Ma, add 1–2 packs of desiccants to absorb residual moisture; replace desiccants every 2–3 months.
• Avoid storing with odorous substances to prevent flavor tainting. Regularly check for mold spots, stickiness, or unusual odors—discard immediately if any spoilage is found.
