Gastrodia Extract Powder Natural Plant Extract Fine Brown Powder

Product Overview

Gastrodia extract powder is a natural plant extract derived from the rhizome of the Gastrodia elata plant, commonly known as Tianma in traditional Chinese medicine. It is available in a fine brown powder form and is widely used in herbal supplements and traditional formulations for its neuroprotective and calming properties.

Common Varieties and Grades

Gastrodia extract powder is typically available in different grades based on purity, yield, and active compound content. Common grades include:

• Standard Grade: Suitable for general use in dietary supplements and traditional formulations.
• High-Purity Grade: Contains elevated levels of gastrodin and other bioactive compounds, often used in research or specialized health products.
• Organic Grade: Grown without synthetic pesticides or fertilizers, certified by recognized organic standards.

Typical Characteristics

The fine brown powder has a mild, earthy aroma and is stable under normal storage conditions. It is typically free from heavy metals, pesticides, and microbial contamination when properly processed. The moisture content is generally kept below 10%, and the particle size is fine enough to ensure uniform mixing in formulations.

Active Compounds and Technical Properties

The primary bioactive compound in Gastrodia extract is gastrodin, a glycoside known for its antioxidant, anti-inflammatory, and neuroprotective effects. Other constituents include gastrodin aglycone, tannins, and polysaccharides. The extract is often standardized to contain 10–20% gastrodin content, depending on the grade and processing method.

Harvesting and Production Process

The Gastrodia elata plant is typically harvested in late autumn when the rhizomes are mature. After harvesting, the rhizomes are cleaned, dried, and ground into a fine powder. The drying process is carefully controlled to preserve the integrity of active compounds. The powder is then sieved to achieve a consistent particle size and stored in airtight containers to prevent moisture absorption and oxidation.

Quality and Grading Standards

Quality is assessed based on several parameters including:

• Moisture content (≤10%)
• Active compound concentration (standardized gastrodin levels)
• Heavy metal and pesticide residue levels (in compliance with international safety standards)
• Microbial load (meeting ISO or FDA guidelines)

Reputable suppliers ensure that their Gastrodia extract powder meets or exceeds international quality benchmarks for herbal raw materials.

Common Uses and Applications

Gastrodia extract powder is widely used in:

• Traditional Chinese Medicine (TCM) formulations for improving circulation and calming the mind
• Herbal supplements targeting stress, anxiety, and sleep disorders
• Neuroprotective formulations for cognitive support
• Functional foods and dietary supplements for overall wellness

Packaging and Export Context

The powder is typically packaged in vacuum-sealed aluminum foil bags or high-density polyethylene (HDPE) pouches with desiccants to maintain freshness. Packaging sizes range from 50g to 25kg per bag, depending on the buyer’s needs. It is commonly exported to regions with growing demand for natural plant-based supplements, including Asia, Europe, and North America.
