Excipients are binding agents necessary for extract preservation.The amount of excipients used in each product varies per formulation but contributes to the stability and solubility of each product. Individual herbs which contain starch do not require excipients.
Stability
Without the correct amount of excipient, granules will absorb atmospheric moisture once exposed to air, clump together and become unstable. This is significant in clinical practice as herb bottles are frequently accessed and exposed to the air.
Solubility
Excipients have varying levels of solubility. Sun Ten most commonly uses non-GMO cornstarch from France as an excipient, however it is not soluble. Other excipients such as Lactose, Maltodextrin, Cyclodextrin are soluble. How extracts dissolve can impact how patients administer the formula (e.g. directly swallowing or mixed in liquid) as well as how easily it can be absorbed in the digestive tract.
