What are the morphological characteristics of this plant?
Gaultheria yunnanensis has evergreen, opposite, ovate to elliptic leaves that are typically 3 to 7 centimeters long with slightly serrated margins and a leathery texture. The plant features woody stems that form a low-growing shrubby habit suitable for montane environments. Small, bell-shaped flowers emerge from the leaf axils, often displaying white or pale pink hues. Following pollination, the plant produces fleshy, globose berries that turn a deep red or purple color when mature. These berries are a defining characteristic of the genus and serve as a vital food source for local fauna.
What is the geographical distribution of this plant?
This plant is native to the high-altitude mountainous regions of southwestern China, specifically within the Yunnan and Sichuan provinces. It thrives in the cool, moist environments characteristic of temperate montane forests and shrublands. Its distribution is closely tied to specific elevations where organic-rich soil and consistent humidity are present. Within these habitats, the species often occupies shaded understories or forest edges. These localized populations are restricted by the unique climatic requirements of the Hengduan Mountains and surrounding highlands.
How is this plant cultivated?
This plant requires acidic, well-draining soil with high organic matter and constant moisture to thrive in temperate or montane climates.
It prefers locations that offer partial shade to protect its foliage from intense direct sunlight. Regular mulching is essential to maintain consistent root temperature and soil humidity levels. Once established, the plant should be watered deeply to prevent the root system from drying out completely.
Careful monitoring of soil pH ensures the plant can effectively absorb necessary nutrients.
What parts of this plant are used medicinally?
This plant Gaultheria yunnanensis provides medicinal benefits through the use of its pericarp and root. The pericarp of the fruit contains specific chemical compounds that contribute to its therapeutic properties. Additionally, the root is harvested to prepare traditional remedies for various health concerns. These different parts are processed according to local medicinal practices to extract their healing potential. Using both the fruit covering and the underground structure allows for a comprehensive application of the plant's natural resources.
According to a study published by "Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica", the essential oil is extracted from the pericarp of Gaultheria yunnanensis. Within the chemical constituents of this oil, methyl salicylate accounts for 99.66%. Grain adsorbents of aluminum hydroxide gel are useful for obtaining higher release rates of the oil at required temperatures. These adsorbents also work to keep the oil stable at room temperature.
