Thanaka (H. crenulata, N. crenulata, L. acidissima L.) is a common tree in Southeast Asia used by the people of Myanmar to create their distinctive face makeup meant for daily sun protection and skincare. Moreover, it is used as a traditional remedy to treat various diseases since it can also be applied as an insect repellent. In this systematic review, the chemical and biological properties of Thanaka have been summarised from 18 articles obtained from the Scopus database. Various extracts of Thanaka comprise a significant number of bioactive compounds that include antioxidant, anti-ageing, anti-inflammatory, anti-melanogenic and anti-microbial properties. More importantly, Thanaka exhibits low cytotoxicity towards human cell lines. The use of natural plant materials with various beneficial biological activities have been commonly replacing artificial and synthetic chemicals for health and environmental reasons as natural plant materials offer advantages such as antioxidant, antibacterial qualities while providing essential nourishment to the skin. This review serves as a reference for the research, development and commercialisation of Thanaka skincare products, in particular, sunscreen. Natural sunscreens have attracted enormous interests as a potential replacement for sun protection products made using synthetic chemicals such as oxybenzone that would cause health issues and damage to the environment.

The herbal ball has been used as a Thai traditional medicine for relieving many diseases including acne. However, the application process of the herbal ball in practice is complicated and time consuming. The objective of this work was to utilize an herbal ball extract to formulate a gel to reach a more favorable use of the herbal ball for acne treatment. An herbal ball consisting of Andrographis paniculata, Centella asiatica, the Benchalokawichian remedy and the stem bark powder of Hesperethusa crenulata was prepared. The obtained herbal ball was steamed and squeezed to obtain the extract. Gel formulations containing the herbal ball extract at concentrations of 0.1, 1 and 5% w/w were prepared based on a carbomer gel. The herbal ball extract had antioxidant (EC50 = 219.27 ± 36.98 μg/mL) and anti Propionibacterium acnes activities (minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) = 31.25 μg/mL). The 5% w/w gel formulation had antimicrobial activity against P. acnes, showing an inhibition zone value of 10.00 ± 1.00 mm. This indicates that the developed gel formulation has potential for acne treatment. In comparison to the traditional method of herbal ball usage, the application of herbal ball extract in the form of gel should be more convenient to use. Full article
