Product Description
Formulated for antibacterial and mucosal protection, providing standardized and traceable high-purity berberine / hydrastine goldenseal extract raw material – Nutralighting ensures every batch of raw material can withstand verification.
Product Description
Goldenseal extract (Hydrastis canadensis Extract) uses berberine and hydrastine as the core indicator components, sourced from a cultivated base (wild resources are CITES-controlled with sustainable supply). Standardized content is based on batch COA. Antibacterial and mucosal protection are its core functions – berberine MIC against Staphylococcus aureus is 0.25 mg/mL and Candida albicans 0.5 mg/ml; hydrastine promotes astringency and hemostasis and strengthens the mucosal barrier. Research shows that berberine-containing extracts show improvement trends in nasal symptoms and mucosal congestion in chronic sinusitis.
Nutralighting goldenseal extract is refined from plant raw materials through a standardized process – ensuring stable berberine and hydrastine content, supporting antibacterial, mucosal protection, and oral-respiratory support functions, suitable for health foods, functional foods, and personal care development.
Goldenseal is one of the most important medicinal plants in the world. The US is the largest consumer, with an annual demand of approximately 500-800 tons. Due to endangered wild resources, trade is strictly regulated under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), making cultivated sources the main supply.

Plant Raw Material Introduction
The raw material is the dried rhizome of Hydrastis canadensis L., a plant of the Ranunculaceae family. Mainly produced in the eastern United States (Missouri, North Carolina) and Canada. Rhizoma Hydrastis is recorded in the European Pharmacopoeia. Hydrastis canadensis, known as ‘yellow root’ in Native American traditional medicine, has a usage history of several hundred years and was included in the US Pharmacopoeia in the 19th century. The main active components are isoquinoline alkaloids: hydrastine and berberine.
Core Effects
The following overview of hydrastis canadensis effects is based on published scientific research and traditional usage; specific efficacy should be evaluated considering the product form and dosage.
Hydrastis canadensis extract has traditional applications in antibacterial and mucosal protection. Hydrastine (0.5-2% content) has astringent and hemostatic effects, reinforcing mucosal barrier function. The berberine component (3-8% content) has broad-spectrum inhibitory effects against various pathogens, with an MIC of 0.25 mg/mL for Staphylococcus aureus and 0.5 mg/mL for Candida albicans. Regarding the respiratory system, Hydrastis canadensis extract (containing 50 mg berberine) shows a trend of improvement in nasal symptoms and mucosal congestion in patients with chronic sinusitis (relevant studies). Hydrastine exerts hemostatic effects by promoting platelet aggregation.
In addition, Hydrastis extract protects oral mucosa, with studies indicating a trend of improvement in oral mucosal hyperkeratosis.
