What is gastrodin?

Gastrodin is a compound derived from the rhizome of the Chinese herb Gastrodia elata, which has been traditionally used in Chinese medicine for its neuroprotective and analgesic effects. It is believed to have anti-inflammatory, antioxidant, and anti-apoptotic properties, which may help to protect the brain from damage and improve cognitive function.

How does it work?

Gastrodin is believed to work by increasing blood flow to the brain and reducing inflammation and oxidative stress. It has been shown to protect against brain injury and neurodegeneration, and may also help to improve cognitive function and memory.

What are the active ingredients that are important for its medicinal properties?

The active ingredient in Gastrodin is gastrodin, which is believed to be responsible for many of its medicinal properties.

What forms does it come in?

Gastrodin is available in capsules, tablets, and tinctures.

When was it first used for medicinal purposes?

Gastrodia elata has been used in traditional Chinese medicine for over 1,500 years, and Gastrodin was first isolated and identified as a compound in the 1980s.

What does Gastrodin help with?

Gastrodin comes from Tian Ma, the tuber of an orchid used in Chinese medicine for a very long time. It is sold as a powder or capsule. Most of its uses involve the head: headache, dizziness and a restless mind.

• Migraines and headaches
  Early evidence — early human studies in China; no trial sizes or doses on file. This is gastrodin's most studied use. Early human studies in China reported fewer and milder attacks. No study sizes, doses or journals are listed in the file.
  Evidence grade C · Traditional tier T0
• Dizziness and vertigo
  Early evidence — modern human research plus long traditional use; study details not on file. Tian Ma has been used for dizziness for hundreds of years. Human research on file backs this use, but without sizes or doses. In lab work, gastrodin steadied nerve signals in brain areas that handle balance.
  Evidence grade C · Traditional tier T0
• Memory and slipping thinking with age
  Early evidence — some clinical studies in older adults; sizes and doses not on file. Some clinical studies in older adults reported sharper thinking and better recall. The file does not list how many people took part, or at what dose. In lab work, gastrodin shielded brain cells from oxidative damage and swelling.
  Evidence grade C · Traditional tier T0
• Getting back on your feet after a stroke
  Evidence doesn't support this — use reports from Chinese hospitals; no trial details on file. In China, gastrodin drips have been used after a clot-type stroke. The file holds use reports, not trial results. Proposed actions include guarding brain cells and lifting blood flow, which is not the same as proof.
  Evidence grade D · Traditional tier T0
• Anxiety and feeling on edge
  Not yet tested in people — lab work on GABA plus user reports; no human trial on file. In lab studies, gastrodin supported GABA pathways. GABA is the brain's main off switch for racing thoughts. Users report feeling more settled and not heavily drowsy, but no human trial is on file.
  Evidence grade insufficient · Traditional tier T0
• Trouble falling or staying asleep
  Not yet tested in people — the same GABA lab work only; no human sleep trial on file. This use rests on lab work, not on people. No human sleep study is on file. So whether it changes how fast you drop off, or how long you stay asleep, is untested.
  Evidence grade insufficient · Traditional tier T0
• High blood pressure
  Not yet tested in people — lab work on blood vessels plus traditional use; no human trial on file. In lab work, gastrodin relaxed blood vessel walls. Chinese medicine has used it beside standard care, often when stress or headache is part of the picture. No human blood pressure trial is on file.
  Evidence grade insufficient · Traditional tier T0
• Nerve pain, including nerve damage from diabetes
  Not yet tested in people — lab and animal work only. Lab and animal work reported fewer pain signals from damaged nerves. Some of that work looked at nerve damage from diabetes. With no human trial on file, this stays an early idea.
  Evidence grade insufficient · Traditional tier T0
• Ringing in the ears (tinnitus)
  Not yet tested in people — traditional use plus a plausible mechanism; no human trial on file. Tian Ma has long been used for ringing in the ears. The idea rests on better blood flow and calmer nerve signals seen in lab work. The library holds no human trial here.
  Evidence grade insufficient · Traditional tier T0

What Gastrodin has not been shown to do

• It has not been shown to replace prescribed blood pressure medicine.
• It has not been shown to replace prescribed seizure drugs, and its seizure use rests on traditional herb formulas only.
• No human trial on file shows that it eases nerve pain; that work was done in lab animals.

How to read this:

The grades rate the human evidence for each single use. A means many matching trials in people. B means one good trial. C means small, mixed or early human studies. D means weak or clashing human evidence. Insufficient means no human study on file, just lab work, animal work or tradition. This page lists options and study findings. It is not advice, and it is not a promise of results. Bring it to your own clinician, above all if you take daily medicine.

What can it help prevent?

Gastrodin has been shown to have preventive effects against the following conditions:

1. Alzheimer's disease and other forms of dementia
2. Mild cognitive impairment
3. Ischemic stroke
4. Parkinson's disease
5. Chronic pain
6. Anxiety and depression
7. Insomnia
8. Epilepsy
9. Migraine headaches
10. Oxidative stress

Which foods are rich in it?

Gastrodin is not found in food sources, as it is derived from the Gastrodia elata plant.

What are possible side effects?

Gastrodin is generally well-tolerated, but some people may experience mild gastrointestinal symptoms such as nausea, diarrhea, or stomach discomfort.

What's the recommended daily dose?

The recommended daily dose of Gastrodin varies depending on the condition being treated and the form of the supplement. It is important to speak with a healthcare provider to determine the appropriate dose for your individual needs.

How many days does it take to work?

The length of time it takes for Gastrodin to work varies depending on the condition being treated and the individual. Some people may notice improvements in cognitive function or pain relief within a few days, while others may take several weeks to see results.

What time of day is best to take it?

There is no specific time of day that is best to take Gastrodin, and it may be taken at any time.

Is it best to take it with or without food?

Gastrodin may be taken with or without food, depending on personal preference and tolerance.
