SUN TEN is one of the largest and oldest manufacturers of Chinese herbal extracts.
SUN TEN is one of the largest and oldest manufacturers of Chinese herbal extracts, Sun Ten is a leader. The facilities in the United States and Taiwan adhere to criteria that surpass those of government regulatory commissions. In many instances, SUN TEN has actually set the standards that the rest of the industry follow. Carefully selected crude herbs are decocted by traditional methods in large vats, the liquid is transferred to a volume reducing device that removes excess water but retains the essential oils, and finally the resulting syrup is spray dried to make granules. Consistently, SUNTEN concentrated extracts are among the most potent available anywhere. Each is, on average, four to six times more potent than raw herbs. SUN TEN offers more than 340 herbal combinations and more than 380 single herbs. What SUN TEN products distinguish from other similar products is the amount of effort that is put into research and quality control. Blending ancient traditions and modern technologies results in world’s finest concentrated Chinese herbal extracts.
All of Sun Ten’s source herbal materials are obtained from private growers and suppliers that meet the specifications established by Sun Ten. Sun Ten secures the resources by maintaining long term relationships with each of the supplying parties and routinely purchasing crops that pass criteria specifications. Purchasing materials directly from the public market can result in problematic source materials with issues such as non-authentic herbal medicinals, herbal medicinals that are not safe due to contamination, toxicity or lacing, and those with inferior constituent ratios. Sun Ten does not accept using any source materials that do not meet the quality standards.
The issue of medicinal authentication is not only a pressing issue but it demands close attention. Simply stated, an herbal medicinal that is not authenticated may not be the correct or desired medicinal. Due to many reasons there may be a large variety of herbal materials being used and sold on the market that are not what we are claimed to be. Sun Ten has established that the herbal medicinals must be of the correct species before we may be implemented into the manufacture process. Verification of authenticity is determined through analytical scientific methods prior to acquisition of the source materials. Sun Ten used the People’s Republic of China Pharmacopeia as the standard reference of correct species.
Detailed Production Process
Raw herb materials are decocted in the traditional manner using water at a specified temperature for a defined time. Special considerations during the manufacturing process include:
Quantity of raw herbs and water
Sequence of herb input
Temperature and time control
Recovery of essentials oils
Historically the majority of classical Chinese herbal formulas have been decocted using water. It offers excellent active constituent extraction as a neutral solvent that doesn't alter the desired actions of the herbs. The water based decoction process draws out the desired constituents and optimizes the formulas unique character. Decocting all the ingredients of a formula together in water yields a final product that is synergistically refined and more potent that the sum of the ingredients if taken individually. Sun Ten uses only water based decoction methods for the entire manufacturing process. This includes essential oil recovery.
The sequence of the herbs within a decoction determines the efficacy of the formulas. For example, the rhubarb (da huang) in Rhubarb & Mirabilitum Combination must be decocted first, followed by the other ingredients to enable the formula to offer the effect “harmonize the stomach and soothe the qi”. Comprehensive chemistries will change upon the sequence of herbal decoction. Sun Ten follows established sequence of decoction appropriate to each formulation because the desired efficacy of the final product depends on it.
Essential Oil Recovery
According to traditional Chinese herbal preparation methodologies, the handling of certain herbs is paramount to ensure efficacy. When preparing aromatic herbs by decoction, it is known that they must be added during the last few minutes of the decoction process. This is because prolonged exposure to the intense heat will damage and evaporate the essential oils that contain essential active constituents needed to deliver the desired effect.
Low temperature vacuum concentration can prevent substantial loss of thermal sensitive constituents.
Fluid bed granulation, the final step of processing by transforming concentrated liquid to granules, is conducted with the addition of an excipient to stabilize the finished product.
The use of excipients in Chinese herbal extracts is necessary to transform concentrated herbal extract liquid into the dry granule. The amount of excipients used in each product varies depending on the characteristics of the herbs within the formulation. Without the correct amount of excipient, the granules, once exposed to air, will absorb atmospheric moisture, clump together and become unstable. Sun Ten uses GMO free cornstarch as an excipient.
The features of spray drying are using less excipients and effectively retaining active constitutes. The spray drying products also proven to have better solubility, in other words, it can have better absorption for human body.
