1. Product Introduction

Nigella Sativa Extract, also commonly known as Black Seed Extract or Black Cumin Seed Extract, is a natural plant extract derived from the seeds of Nigella sativa. Its core biologically active ingredients are concentrated in seed volatile oil, withThymoquinone (TQ) serving as the primary functional monomer component.

With a medicinal and edible history of more than 2,000 years, Nigella sativa is mainly planted in Yunnan and Xinjiang, China. Modern pharmacological research confirms that Thymoquinone possesses multiple powerful bioactivities, including anti-inflammation, hypoglycemic, lipid-lowering and antihypertensive effects. As a high-value natural active raw material, it has broad application prospects in disease adjuvant treatment and new drug development.

Thymoquinone

Thymoquinone production begins with the raw material, which is commonly a black seed from the Nigella sativa plant. The seeds are then crushed and processed to remove any contaminants. The refined filtration technique helps to cleanse and boost the quality of thymoquinone. Next, the thymoquinone is extracted with ethyl alcohol. This procedure helps to preserve the beneficial chemicals found in thymoquinone. Finally, the thymoquinone is purified using sophisticated filtering. This procedure assures that the thymoquinone has the maximum quality and purity.

2. Professional Production Process

We adopt standardized, low-loss and high-purity extraction and purification technology to ensure stable active ingredient content and high product safety:

Raw Material Pretreatment: Select high-quality Nigella sativa seeds, crush raw materials and remove impurities to ensure raw material purity.
Refined Filtration: Adopt multi-stage refined filtration technology to purify raw materials and improve the basic quality of intermediate products.
Ethanol Extraction: Use food-grade ethanol as the extraction solvent to fully retain active chemical components of thymoquinone and avoid active loss.
Advanced Purification: Complete deep purification through sophisticated filtering equipment to maximize product purity, stability and safety.

What are the effects of thymoquinone?

Nigella Sativa is mainly distributed in Yunnan and Xinjiang, China. Its seeds have been used as both medicine and food for more than 2,000 years and can be used to treat a variety of diseases, such as skin diseases, conjunctivitis, diabetes, hypertension, bronchitis, etc.

In recent years, more and more studies have found that black cumin seeds and their active ingredient thymoquinone have antimicrobial effects.
Studies have shown that black cumin seed extract has inhibitory effects on a variety of pathogens, such as Staphylococcus aureus and Pseudomonas aeruginosa.
This shows that black cumin seeds and their active ingredient thymoquinone can be used as anti-dermatophyte drug ingredients and can be used to treat fungal skin infections.
Cell experiments have also found that thymoquinone can inhibit the expression of Epstein-Barr virus genes.
