Notable Constituents:
- Mogroside
A natural, non-caloric triterpene glycoside compound, roughly 250 to 425 times sweeter than table sugar (sucrose) that cannot be absorbed by the stomach or small intestine, meaning it has zero calories, zero carbohydrates, and a zero glycemic index, so does not spike blood sugar levels. Furthermore, when it reaches the large intestine, it is fermented by beneficial gut bacteria which then use the sugars as a prebiotic increasing the number of several strains, including Bacteroides, Lactobacillus, Prevotella, Megasphaera, and Olsenella, while inhibiting harmful species such as Clostridium XlVa, Dorea, and Desulfovibrio (Xiao et al., 2021). This increases the production of short chain fatty acids which enhances the expression of tight junction proteins, improving intestinal barrier function and reducing permeability (Huang et al., 2025). It is stable under high heat (up to 100 – 150°C) and across a wide pH range, making them suitable for cooking and baking. Different forms exist (such as Mogroside II, III, IV, V, and VI), with Mogroside V being the primary commercial standard used in high-purity sweeteners.
- Siamenoside I
A second natural, non-caloric triterpene glycoside compound, roughly 300 times sweeter than sucrose, used as a sweetener in China.

Reference Notes:
Individual herb information has sourced mainly from TCM Wiki and American Dragon for basic data and then updated manually with my own notes. Zhou, Xie and Yan (2011): Encyclopedia of Traditional Chinese Medicines, Vol. 5, and A+ Medical Encyclopaedia have been used for entries not available from those sources with additional material searched for and filled in where available. Western herbs not appearing in the Chinese literature have used Ross (2010): Combining Western Herbs and Chinese Medicine: A Clinical Materia Medica, White Rabbit Institute of Healing and therapeutika.ch. Choices of which source to use or combine have been my own.
