“…The authors selected 47 human dental roots, five roots without bacterial inoculation (negative control), the remaining roots were inoculated with Enterococcus faecalis and divided into groups, which were treated with the products for 5, 10, and 15 min; five roots were randomly selected as positive controls. All irrigation solutions, including the T. officinale extracts, decreased the number of E. faecalis colonies, though hypochlorite was the most effective product (Shafiq & Al‐Hashimi, ). More recently, T. officinale showed inhibitory activity against oral cavity microbes E. faecalis and Streptococcus salivarius , thus suggesting a potential role of the herb in control of dental caries and endodontic infections (Sangeetha & Devaraj, ).…”

Plants belonging to the genus Taraxacum have been used in traditional healthcare to treat infectious diseases including food-borne infections. This review aims to summarize the available information on Taraxacum spp., focusing on plant cultivation, ethnomedicinal uses, bioactive phytochemicals, and antimicrobial properties. Phytochemicals present in Taraxacum spp. include sesquiterpene lactones, such as taraxacin, mongolicumin B, and taraxinic acid derivatives; triterpenoids, such as taraxasterol, taraxerol, and officinatrione; and phenolic derivatives, such as hydroxycinnamic acids (chlorogenic, chicoric, and caffeoyltartaric acids), coumarins (aesculin and cichoriin), lignans (mongolicumin A), and taraxacosides. Aqueous and organic extracts of different plant parts exhibit promising in vitro antimicrobial activity relevant for controlling fungi and Gram-positive and Gram-negative bacteria. Therefore, this genus represents a potential source of bioactive phytochemicals with broad-spectrum antimicrobial activity. However, so far, preclinical evidence for these activities has not been fully substantiated by clinical studies. Indeed, clinical evidence for the activity of Taraxacum bioactive compounds is still scant, at least for infectious diseases, and there is limited information on oral bioavailability, pharmacological activities, and safety of Taraxacum products in humans, though their traditional uses would suggest that these plants are safe.

“…Aqueous and ethanolic extracts of the leaves and roots of this plant are effective against pathogenic microorganisms, including Escherichia coli and Staphylococcus aureus [12,13], whereas the root extracts show greater bactericidal properties against S. aureus [13]. Leaf and root extracts can be used in dentistry as a disinfectant that strongly inhibits the growth of Enterococcus faecalis [14]. In vivo studies on guinea pigs have shown very good efficacy of Taraxacum officinale leaf extract in the treatment of tracheal inflammation [15], similarly to in vivo mouse studies on acetic acid-induced angiogenesis [16].…”

Effect of the Addition of Dried Dandelion Roots (Taraxacum officinale F. H. Wigg.) on Wheat Dough and Bread Properties

et al. 2021

Dried and crushed dandelion roots (Taraxacum officinale F. H. Wigg.) (TO) were used as a formulation additive (at the amount of 0, 1, 3, 4, 5, and 6 g 100 g−1 flour) to wheat bread. The farinographic properties of the dough and the physical and chemical properties of the bread were evaluated. It was found that the addition of dried flour caused a significant decrease in water absorption by the flour (1% and higher TO level), an increase in the development time (from 2% to 5% TO addition) and dough stability (3% and 4% TO level), and an increase in dough softening (4% and higher TO level). As the substitution of TO for wheat flour increased, there was a gradual decrease in loaf volume, an increase in specific weight and crumb hardness, and a darkening of the crumb color. The total polyphenol content increased linearly with the percentage increase of dried root additions TO from 0.290 to 0.394 mg GAE g−1 d.m., which translated into an increase in the antioxidant activity of the bread. It was found that dried crushed roots of Taraxacum officinale can be a recipe additive for wheat bread; however, due to their specific smell and bitter aftertaste, the level of this additive should not exceed 3 g 100 g−1 flour.

“…The only report in which a Taraxacum extract was compared to another natural antibacterial substance besides other plants extracts evaluated the use of T. officinale extract as an irrigation agent in endodontic treatments against E. faecalis in root canal infections. Leaf and root extracts at 0.7% were slightly active but propolis was more effective for this purpose [53]. In the case of commercial preparations, high activity has been reported for a commercial T. officinale ethanolic extract, showing antibacterial activity against H. pylori at 20 mg/mL with 26% inhibition but no observable activity for C. jejuni [54].…”

Plants have been used in traditional medicine for centuries as antibacterial and antifungal agents. Taraxacum spp., commonly known as dandelion, is a well-known herbal remedy with a long history; however, limited scientific information is available to explain its traditional use. This review aims to provide current information and a general overview of the available literature concerning the antibacterial and antifungal properties of the Taraxacum genus to support its potential as a powerful herbal medicine. Though Taraxacum has demonstrated that it is capable of inhibiting the growth of a wide range of bacteria and fungi, the technical aspects of methodology lack standardization, and, therefore, the overall results of processing are difficult to compare between studies. Phytochemical composition and antimicrobial activity in Taraxacum are neither directly related, nor does the published data provide sufficient information for identifying the group of unique extraction conditions that are optimal against specific microorganisms. Antimicrobial research indicates that this plant is a promising species for treating several common infections in humans, animals, and plants.
