Kan Herb Company has earned its reputation for excellence and integrity by paying meticulous attention to every aspect of manufacturing and quality control. We follow current Good Manufacturing Practices, extract ingredients using state-of-the-art methods, and keep detailed records every step of the way.

To ensure that our finished products are of consistently high quality, and to prevent materials from being adulterated or contaminated, we have established manufacturing controls that meet or exceed recognized current Good Manufacturing Practices (cGMPs) set forth by the United States Food and Drug Administration. Our internal manufacturing controls provide documented proof that correct procedures are consistently followed, at each step in the manufacturing process, every time the product is made. Our cGMPs assure the purity, consistent composition, and quality of all of our finished products.

Extensive controls cover the sanitation and hygiene of our facilities, utensils, production materials and containers, as well as testing specifications and limits for heavy metals, pesticides and bio-burdens. Utilizing qualitative and quantitative analysis, Kan Herb Company's quality control unit approves all procedures, specifications, controls, tests, and examinations that impact the purity, quality and composition of an ingredient or product. All raw materials and finished dietary products are inspected by our QC unit; complete inspection records and laboratory tests are maintained.

Controls are also in place for handling materials throughout each step of production, such as worksheets and traveling tags, assuring consistency from batch to batch, easy monitoring, and averting opportunities for adulteration. All bulk products are stored in quarantine before entering our production cycle. Products are labeled with a formula identification number, lot number, receiving date, and expiration date for easy tracking by our Quality Control department. Bottles are capped and sealed with a tamper-proof covering and shrink-wrapped.

California, the site of our production facility, has some of the most rigorous safety standards in the world. Our adherence to these high standards and the cGMPs we have established for our company set us apart from the majority of Chinese herbal companies.

Once the herbs have passed quality inspection and testing, they are compounded into a formula and painstakingly blended and ground, making the active ingredients more accessible. They are processed according to Kan Herb Company's unique extraction methodology, under the supervision of biochemist Justin Wilson, Ph.D., a former Henry Fellow at Oxford and researcher at NIH. Only distilled water is used in extraction to avoid any contamination that may be found in tap water.

Excellent manufacturing techniques are required to yield the high concentration of active ingredients necessary for effective herbal therapy. Due to the molecular composition of the herbs, some herbs extract well in water, while others, such as ginseng, require alcohol to extract the active ingredients (such as ginsenocides). Kan Herb Company's innovative closed system, water-alcohol matrix extraction process, ensures that all active ingredients are captured, while letting no volatile oils escape. With strict control of temperature and timing, the herbs are heated just long enough to extract the active constituents, while avoiding carmelization or denaturing of the herbs.

Batch to batch consistency of each lot of finished liquid extract is verified. Each product is referenced against up to four prior batches, confirming proper extraction as indicated by consistent color, appearance, odor and taste. The highest level of active constituents are included in our final product, rendering small batches of fresh, full spectrum herbal extracts with an 8:1 potency. Our extracts are of remarkable character, enriched with the individual flavors and clinical potency that the ancient medical masters intended.

Liquid extracts are the most bioavailable form of delivery available, surpassing any other type of concentration, including tablets or concentrated powders. Easy to digest, they are ideal for those with weak digestion or difficulty swallowing pills, such as in the case for many older people and children. Liquid extracts are assimilated within 15 minutes of ingestion, and are excellent for acute conditions, such as the sudden onset of a cold, flu or virus.

After authenticating each raw herb with organoleptic testing, performing pesticide screens on each lot, as well as aristolochic acid and heavy metal testing, each formula is compounded, finely milled and thoroughly blended. Kan Herb Company uses steam heat and pressure in a unique closed extraction system, ideal for the breakdown of the cellular structure of the herbs. This proprietary process mixes the constituents and reduces the microbiological load, while maintaining all active ingredients, including volatile oils.

The resulting potent and bioavailable powdered material is tableted, utilizing varying levels of direct cold compression. Natural binders are only used when absolutely necessary. For preservation and easy swallowing, the tablets are coated with micro cellulose, a natural vegetable based coating.

The tablets are tested to ensure quality and consistency. Meticulous tests for disintegration, weight and uniformity, hardness and friability are performed. Disintegration tests follow USP methodology monograph 2040 for nutritional supplements. Kan Herb Company's tablet disintegration rate is 30 minutes, with full assimilation normally occurring in 4 to 6 hours, the industry standard. The weight and uniformity of our tablets is confirmed by following USP methodology monograph 2091 for weight variation of nutritional supplements.

Hardness tests are conducted following standard industry practices; a machine gently applies pressure to determine their breaking strength, or hardness; they are distressed in a tumbler to determine friability and breakage. This thorough testing assures a tablet that is uniform, fresh, potent, and bioavailable, as well as carrier free.

At Kan Herb Company, we are committed to ensuring our products remain fresh throughout their shelf life. Sterilized bottles are filled using clean automated bottle technology, and each bottle is shrink-wrapped to protect against tampering. Wherever possible, we use recycled materials for packaging.

Well preserved in the alcohol solution, liquid extracts have a very long shelf life. Evaporation of alcohol is the only limiting factor, in which case the herbs will eventually congeal. Sealing the bottle tightly after use will prevent this.

With proper storage, the shelf life of Kan Herb tablets is 3 years. Once opened, exposure to air, moisture, heat and light will accelerate the formula's natural process of erosion. Seal the bottle after each use and store tablets in a cool, dry, dark place.

Kan Herb Company is highly conscious of the quality of materials used in the manufacturing and packaging of our products. We offer our customers the choice of herbal extracts delivered in high-density polyethylene (HDPE) bottles. HDPE bottles are recommended by the FDA and are a recyclable material, used throughout the industry for the packaging of liquid extracts and tablets. HDPE bottles are resistant to impact, moisture, and permeability, delivering fresh, liquid extracts with zero breakage.
