Premium Damiana Extract – Traceable Mexican Turnera diffusa Leaf Extract

Damiana Extract is a strong plant-based powder made from the leaves of the Turnera diffusa plant, which is harvested in Mexico and parts of tropical Central America.This ingredient is known for helping with reproductive health, reducing mild anxiety, and boosting emotional well-being.It’s different from basic leaf powder because it has a consistent strength and quality.Every batch is tested using HPTLC to make sure it’s not mixed with other similar plants like Turnera ulmifolia.It comes in three strength levels – 4:1, 10:1, and 20:1 – and a version that has 8% total flavonoids.Each type is checked for harmful substances like heavy metals, pesticides, and bacteria to make sure your products are safe and effective every time.

Why Choose Us

Our research team carefully finds the active parts of the plant.We have three production lines that make over 2,000 tons per year.

Our lab has special machines like UPLC, HPLC, GC-MS, ICP-MS, and HPTLC to ensure the product is powerful and clean.

We have certifications like ISO9001, HACCP, HALAL, KOSHER, and organic.

Our organic products are made separately to avoid mixing with other materials.Every order comes with a certificate, COA, MSDS, and tests done by SGS or Eurofins.

We also offer custom mixes and flexible packaging.

Raw Material Origin & Traceability

Origin & Variety:

We get real Turnera diffusa leaves only from Mexico and tropical Central America, not from similar plants like Turnera ulmifolia.The starting materials are split into wild and carefully grown types.

Raw Material Grading:

· Dietary Grade: Uses mature, clean leaves with no mold, dry branches, or dirt; has low levels of pesticides and heavy metals; used for 10:1, 20:1, and 8% standardized products.

· Economy Grade: Uses broken leaves and scraps; cheaper option; used for 4:1 extraction and mixed with other herbs.

· Organic Grade: Grown in organic farms in Mexico; has USDA and EU organic certificates; has full tracking; made in a special area to avoid mixing.After harvest, leaves are air-dried, dusted, cleaned, and stored under controlled conditions.

Solubility & Stability Profile

Solubility:

· Standard Damiana Extract: Soluble in ethanol and propylene glycol; slightly soluble in cold water (may precipitate); insoluble in oils (requires emulsifiers for topical use).

· Water-Soluble Variant: Cyclodextrin-encapsulated; fully dispersible in hot or cold water; ideal for beverages and oral liquids.

Stability:

· Temperature: Stable at ≤60℃; heating above 85℃ can break down flavonoids and other important parts.

· PH Range: Works best in pH 5.2–6.5; too acidic or basic can break it down.

· Light: Stable when dry and stored away from light; water-based solutions can slowly oxidize if kept for too long.

· Hygroscopicity: 4:1 > 10:1 > 20:1 > 8% standardized (higher purity means less moisture absorption).

Manufacturing Process

Step	Process Details
Pre-treatment	HPTLC verification; remove inferior species, dirt, mold; low-temp drying at 40–45℃; grind to 20–30 mesh
Extraction	4:1: Water extraction at 75–80℃ 10:1/20:1: 50% ethanol reflux at 60–65℃
Filtration	Multi-stage: cloth bag → plate-and-frame → precision bag filter
Concentration	Vacuum evaporation ≤60℃; ethanol recovery and reuse
Purification	4:1: No resin 10:1/20:1: Cold settling 8%: D101 macroporous resin enrichment
Drying	Spray drying (4:1, 10:1, 20:1) at inlet 150℃, outlet ≤75℃ Vacuum drying (8%) at 42–48℃
Finishing	Sieving, uniform mixing, vacuum-sealed aluminum foil packaging
Testing	HPLC, ICP-MS, GC-MS, microbiology; COA & MSDS issued

Quality Assurance

We follow a full traceability system from the farm to the finished product.Every batch is tested for identity (HPTLC), strength (HPLC), heavy metals (ICP-MS), pesticide residues (GC-MS), and contamination.Our certificates include ISO9001, HACCP, HALAL, KOSHER, ISO22000, and FSSC22000.Organic batches have USDA and EU organic certifications.We also offer third-party testing by SGS and Eurofins.
