FC-Cidal™ supplies a proprietary blend of herbs and herbal extracts, which function to support healthy GI function.* Herbs, spices and botanical preparations often exhibit antimicrobial properties due to a wide array of terpenoid and polyphenolic compounds. Culinary herbs have long been used to control pests and food-borne yeasts and molds in the context of food safety. Thyme, for example, is an aromatic oil enriched in monoterpenes. The thymol content of thyme oil can be 30-70%, while the carvacrol content ranges between 3 and 15%. Both of these compounds possess antimicrobial and antiviral properties.
