Black Ginger FAQ

Frequently Asked Questions: Kaempferia parviflora (กระชายดำ)

1. What is Black Ginger and how does it differ from common ginger?

While both belong to the Zingiberaceae family, Black Ginger (Kaempferia parviflora) is botanically distinct. Locally known in Thailand as Krachai Dum (กระชายดำ), its rhizome features a deep purple-black interior. Unlike common ginger which is used for digestion, Black Ginger is prized for its high concentration of Polymethoxyflavones (PMFs), which support metabolic health and mitochondrial function.

2. Why is "standardization" important for Black Ginger extracts?

Raw rhizome powder varies wildly in quality. PT Sumatera Pasak Bumi standardizes its extract to 10% Polymethoxyflavones (PMFs). This ensures that every batch contains a verified therapeutic concentration of the primary bioactive markers, such as 5,7-dimethoxyflavone, providing consistent results for industrial and retail applications.

3. Where does PT Sumatera Pasak Bumi source its Black Ginger?

Our Black Ginger is sourced from high-altitude farms managed by Thai Hmong (ชาวม้ง) hilltribe communities in Northern Thailand. The plant requires a specific geopedology—tropical soil at elevations above 1,000 meters—to synthesize the maximum level of flavonoids. Our tribal partnership ensures ethical sourcing and superior phytochemical density.

4. What are the primary bioactives in your extract?

The extract is concentrated for Polymethoxyflavones (PMFs). These unique methoxyflavones are currently the subject of international research regarding their ability to activate AMPK (AMP-activated protein kinase) and improve cellular energy metabolism.

5. Can Black Ginger be combined with Tongkat Ali?

Yes. In traditional Southeast Asian ethnobotany, Black Ginger and Tongkat Ali are often used synergistically. While Tongkat Ali focuses on hormonal optimization (via eurycomanone), Black Ginger addresses physical endurance and blood flow (via PMFs), making them a powerful combination for athletic performance and vitality.

6. What is the shelf life and storage protocol?

Our standardized extracts have a shelf life of three years when stored in a cool, dry place away from direct sunlight. Because our extracts contain zero excipients (no rice flour or fillers), they are highly stable but sensitive to extreme humidity.
