#WoundHealing

A new study has found that humans’ wounds heal significantly more slowly than those of other mammals, raising intriguing questions about our biology and evolutionary trade-offs. The research, recently profiled by The New York Times, has major implications for medicine and health, especially for Thailand’s ageing population and those managing chronic health conditions.

The discovery comes from a comparative investigation into the healing rates of skin wounds in humans versus other mammalian species, using both laboratory models and clinical data. According to the report, researchers found that while most mammals—such as mice, pigs, and dogs—heal wounds within days or weeks, similar injuries in humans often require much longer timeframes. This discrepancy holds true even when accounting for differences in body size, environmental factors, and medical intervention.

Few substances straddle the worlds of ancient ritual, traditional medicine, and modern industry quite like lac (ครั่ง)—the intriguing resin secreted by the lac insect, Laccifer chinensis. Known in Thai as ครั่ง and in Chinese as จุ้ยเก้ง, this natural exudate has colored textiles, sealed documents, delivered vivid reds in temple murals, and, more quietly, worked as a healing agent in traditional remedies across Asia for centuries. Today, as scientists revisit the pharmacological potential of natural compounds, lac is in the spotlight once again—not only for its rich legacy but for surprising early evidence supporting some of its traditional uses. What makes this glossy, carmine-tinted resin so special, and how can today’s health-conscious readers separate myth from material fact?

Within the vibrant kitchens and bustling markets of Thailand, the humble blood cockle—known locally as หอยแครง (hoi kraeng)—holds not only a cherished place at the dining table but also a deeper, centuries-old role in the realm of healing. While many Thais relish this mollusk in spicy salads and street food delicacies, few realize that the shell of Anadara granosa, the scientific name for this ark clam, also occupies a storied position in Thai traditional medicine. As scientific curiosity grows about natural remedies, Anadara granosa has become the subject of intense investigation, raising compelling questions about the intersection between ancestral knowledge and contemporary health research.

The graceful, trailing roots and glossy green leaves of Ficus benjamina—known to generations of Thais as ไทรย้อย or the weeping fig—have long played a role in the spiritual, ecological, and medicinal landscapes of Thailand. Amid the lush chaos of urban and rural Thailand, ไทรย้อย stands as both a symbol of serenity and a quiet reservoir of traditional healing knowledge. Today, a surge of scientific inquiry is illuminating the plant’s potent bioactive compounds, validating some age-old practices, and pointing toward future medical opportunities.
