National Institution of Drug Clinical Trial, Xiangya Hospital, Central South University, Changsha, China.
Compound methyl salicylate liniment (Ammeltz) is composed of various components, such as methyl salicylate, menthol, camphor, chlorpheniramine maleate, and thymol. It was approved for listing in China in 2011. The purpose of this phase Ⅳ clinical trial was to evaluate the safety and efficacy of Ammeltz in a real-life environment in China.

As a developed economic region in China, the problem of heavy metals (HMs) pollution in the Yangtze River Delta has become increasingly prominent. As an important evergreen broad-leaved tree species in southern China, the camphor tree cannot only be used as a street tree but also its various tissues and organs can be used as raw materials for Chinese herbal medicine. In order to explore whether heavy metal contamination in the region threatens the safety of camphor trees as pharmaceutical raw materials, we collected the bark and leaves of the tree most commonly used for pharmaceuticals in Yixing City.

Article Synopsis
- The study analyzes how potentially toxic elements (PTEs) distribute in smoke particles and ashes from burning various biomass materials.
- It reveals that certain components like camphor leaves and branches have higher concentrations of specific PTEs, such as arsenic and chromium, particularly in smoke and residual ashes.
- The research indicates that temperature affects the bioavailability of PTEs, which decreases as temperatures rise, suggesting significant environmental risks from these elements in combustion byproducts.
Curcumin on Camphor-Induced Chemical Burn on the Palate: Report of a Peculiar Self-Inflicted Case.

Intraoral soft tissue injuries occur due to physical, chemical, or thermal agents, which may present as ulcerations, burns, desquamation, and gingival recession. Camphor is one such substance easily available in many Indian households and is not a very well-recognized potentially fatal toxic compound. Here, we report the first case of an intraoral soft-tissue burn in a geriatric female, as a result of direct injury to tissues due to the application of crushed camphor powder to manage tooth pain at home, which was successfully treated with 2% Curcuma longa.

Air Quality Studies, Department of Civil and Environmental Engineering, The Hong Kong Polytechnic University, Hong Kong, China.
Due to the high health risks associated with indoor air pollutants and long-term exposure, indoor air quality has received increasing attention. In this study, we put emphasis on the molecular composition, source emissions, and chemical aging of air pollutants in a residence with designed activities mimicking ordinary Hong Kong homes. More than 150 air pollutants were detected at molecular level, 87 of which were quantified at a time resolution of not less than 1 hour.
