According to a study published by "Biomolecules", plants of the genus Wikstroemia have been used as traditional medicines to treat diseases like pneumonia, rheumatism, and bronchitis. Within this genus, the biflavonoid chamaejasmine was found to be the most potent of ten flavonoids isolated from W. dolichantha at inhibiting DNP-specific IgE-induced degranulation in RBL-2H3 cells. When 0.5% chamaejasmine was applied topically to DNCB-sensitized SKH-1 hairless mice for 2 weeks, it attenuated clinical symptoms such as itching, dryness, erythema, and edema. This 0.5% concentration also inhibited DNCB-induced increases in total IL-4 and IgE levels in serum while reducing dermal thickness and mast cell infiltration. Furthermore, the treatment improved skin barrier function and increased epidermis moisture.
The primary pharmacological activities of this plant are shown in the list below.
- anti-allergic
- anti-atopic
What medicinal compounds this plant contains?
This plant contains the medicinal compounds aromadenriin, chamaejasmine, padmatin, and taxifolin. These specific phytochemicals contribute to the diverse biological activities found within the species. Researchers study these molecules to understand their potential therapeutic properties in various medical applications.

According to a study published by "Nutrients", an EtOH extract of Wikstroemia dolichantha (WDE) was investigated for its anti-atopic effects using a 1% WDE topical application. The composition of WDE was determined using HPLC/MS, which tentatively identified 4 flavonoids: taxifolin, aromadendrin, padmatin, and chamaejasmine. This 1% WDE application was applied daily to mice for 2 or 3 weeks to treat induced dermatitis. The WDE treatment helped reduce DNCB-induced increases in serum IL-4 and IgE levels. Additionally, the application of 1% WDE decreased TEWL and increased skin hydration to improve skin barrier function.

According to a study published by "Biomolecules", plants of the genus Wikstroemia have long been used as traditional medicines to treat diseases like pneumonia, rheumatism, and bronchitis. This research specifically investigated the effect of chamaejasmine, a biflavonoid from W. dolichantha, on atopic dermatitis-like skin lesions in a murine model. Ten flavonoids were isolated from W. dolichantha to examine their anti-allergic activities through the measurement of beta-hexosaminidase release. Among these ten flavonoids, chamaejasmine was found to most potently inhibit DNp-specific IgE-induced degranulation in RBL-2H3 cells. The topical administration of 0.5% chamaejasmine attenuated clinical symptoms such as itching, dryness, erythema, and edema. Furthermore, 0.5% chamaejasmine inhibited DNCB-induced increases in total IL-4 and IgE levels in serum while improving skin barrier function.
