Our Six Main Areas of Concentration

Suitable site selection
We carefully prefer geographically isolated and pollution-free agricultural land is selected for contract cultivation of medicinal materials.
Surpassing HSA Safety Standards
Beyond heavy metal testing—we rigorously assess pesticides, impurities, and active compounds to ensure our herbs meet the highest safety and potency.
No Preservatives & Sulphur
We use refrigerated storage to minimise deterioration, preserving the freshness and potency of our herbs without preservatives or sulphur fumigation.
Precision impurity filtering
Multiple powerful magnet rods are installed in the filter unit to remove iron impurities, and the use of metal filtration is developed.
Scientific testing
We follow pharmaceutical factory standards and Taiwan safety regulations, and conduct tests to ensure the quality and safety of medicinal materials.
Harvest on time
To ensure the best effect of the medicinal materials, and through farmers' rich experience, we control the optimal harvesting schedule of various medicinal materials.
Traditional Processing Method vs. Authentic Processing Method


The traditional method is time-consuming and involves soaking in water, which causes the key active ingredient, baicalin, to hydrolyse easily. In contrast, the Authentic Method avoids over-processing, preserves more of the active ingredients, and results in a higher baicalin content. (Bar graph shows significantly higher baicalin content in the Authentic Method compared to the Traditional Method.)
Roots of Wellness

Our herbs are sustainably grown by experienced farmers in pesticide-free fields to ensure purity from the source.

Hand-harvested at peak potency, our herbs are nurtured with traditional farming methods and modern safety standards.

Each herb is carefully selected and cut by hand, preserving its active compounds for maximum efficacy.

Our herbs are freshly processed on-site immediately after harvest to lock in their natural benefits and minimise oxidation.

Our herbal fields are regularly maintained and monitored to ensure optimal growth conditions and consistency.

Every root and stem is handled with care, from soil to harvest, to guarantee traceability and trust.

Harvested entirely by hand, our herbs are collected with care to preserve their natural integrity.

Freshly harvested herbs are laid out for natural sun-drying, allowing them to cure slowly for optimal efficacy.

We rely on skilled local farmers whose careful harvesting ensures quality at every stage of cultivation.

Each plant is individually tended to and hand-cut, demonstrating our commitment to quality over mass production.

Our cooperative farming model supports rural communities while ensuring responsible, small-batch herbal production.

Herbs are naturally sun-dried and evenly spread to retain their colour, aroma, and medicinal value.
