“…2 B. pilosa has been used in the treatment of hepatitis, laryngitis, conjunctivitis, abscesses, headache, urinary infections and digestive disorder and it has been exhibited varieties of biological and pharmacological activities, which include antimalarial, antihyperglycaemic, antileukemic, antitumor, antibacterial, antimicrobial, anti-inflammatory and antioxidant activities. [2][3][4][5][6][7][8][9][10][11][12][13] Practically, all parts of B. pilosa are exhibited therapeutic applications. 13 Therefore, the whole plant materials have been used in the traditional medicine for the preparation of decoctions or infusions for internal consumption.…”

Bidens pilosa finds therapeutic applications in the traditional medicine. In the present study, we aimed to evaluate the antioxidant activity of various extracts obtained from the leaves and stem-bark of B. pilosa by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and ferric reducing power assay. We also aimed to determine the total phenolic contents (TPCs) by Folin-Ciocalteu colorimetric method and total flavonoid contents (TFCs) by the aluminium chloride colorimetric method. Various solvent extracts were obtained from the leaves and stem-bark of B. pilosa by maceration and hot solvent extraction techniques. The extracts from leaves and stem-bark exhibited radical scavenging activity in the ranges of 4.40 ± 1.02-81.18 ± 1.14% and 5.92 ± 2.16-79.34 ± 8.43%, respectively at concentrations of 200-3,000 µg/mL. The positive control, ascorbic acid exhibited radical scavenging activity in a range of 55.17 ±1.89-88.12 ± 1.31% at the same concentrations. Additionally, the methanol extracts from both leaves and stem-bark were found to be the most potent with IC50 values of 848.54 and < 200 µg/mL, respectively. The positive control, ascorbic acid exhibited an IC50 value < 200 µg/mL. Furthermore, the extracts from the leaves and stem-bark exhibited ferric reducing power in the ranges of 0.095 ± 0.017-1.175 ± 0.084 and 0.093 ± 0.006-1.100 ± 0.065, respectively at concentrations of 5-100 µg/mL. The positive control, ascorbic acid exhibited a ferric reducing power in the range of 0.326 ± 0.00-1.213 ± 0.078 at concentrations of 5-100 µg/mL. In addition, the TPCs of extracts from the leaves and stem-bark were determined to be in the ranges of 9.03 ± 2.34-179.31 ± 0.96 and 10.93 ± 1.04-154.04 ± 2.15 mg GAE/g of DW of extract, respectively. Similarly, the TFCs of extracts from the leaves and stem-bark were determined to be in the ranges 1.28 ± 0.05-29.33 ± 4.19 and 1.89 ± 0.58-27.75 ± 2.67 mg QE/g of DW of extract, respectively. From this study, we concluded that various extracts obtained from B. pilosa showed a moderate to strong radical scavenging and ferric reducing power and possessed a significant amount of TPCs and TFCs.

“…It is recorded that in folk medicine, the whole plant, the aerial parts (flowers, leaves, seeds and stems) and the roots of B. pilosa serve the purpose of treating more than 40 illnesses namely, inflammation, immunological disorders, digestive disorders, infectious ailments, wounds, cancers, metabolic syndrome. 102,[104][105][106][107] In this context, Bidens pilosa L. is usually prepared as a dry powder, maceration, decoction, or tincture 108 and is usually taken orally. It is also used to good effect externally.…”

Ageratum conyzoides L., Tridax procumbens L. and Bidens pilosa L. are well known plant species of the Asteraceae family that are considered weeds in intensive agriculture. These weeds are traditionally known to have medicinal properties and have been used for therapeutic treatments. However, it is only the lack of proper knowledge, awareness and screening that have limited their use in pharmaceutical sectors. This review attempts to consolidate the traditional, phytochemical and pharmacological studies that have been carried out on Ageratum conyzoides L., Tridax procumbens L. and Bidens pilosa L., which we note are widely spread throughout the world. This study was conducted through a coherent search on Ageratum conyzoides L., Tridax procumbens L. and Bidens pilosa L. with respect to traditional uses, phytochemical and pharmacological studies that have been performed on these three agricultural weeds all over the world. An exploration of reported descriptions of the potential medical importance of three agricultural weed species (A. conyzoides, T. procumbens and B. pilosa) has been presented. The present review would encourage further clinical investigations into these three plants and their extracts to more closely define the range of uses of these herbs for clinical applications. This, in turn, would give a clear understanding whether these weed species might be targeted to be conserved in a sustainable manner rather than eradicated.

Bidens pilosa L. can be found everywhere in warm and humid regions. The plant has been used as a food and drink supplement, and as medicinal herbs for a long time by people from various places. The assortment of activities of B. pilosa in treating diseases gives a remarkable possibility to explore and develop its utilization for various medicinal purposes. In this mini-review, we explored the application of B. spilosa as herbal medicine for mouth health, specifically mouthwash. Until now, there is no information about the application of this plant for mouthwash. The use of alcohol, cetyl pyridinium, chlorhexidine, and triclosan as active ingredients in mouthwash can control plaque. However, the long-term use of these compounds may show side effects, for instance, changes in taste, and teeth and oral stains. Based on the result, it can be concluded that the B. spilosa plant contains diverse groups of compounds, such as polyacetylenes, flavonoids, and tannins, which are responsible for its various activities. The B. spilosa extracts are non-toxic and have potential active compounds in mouthwash formulation, due to their antimicrobial action against a wide range of microbes, particularly oral microbes and it has additional activities such as anti-inflammation, analgesic, and antioxidant.
