Scientific name: Mussaenda roxburghii Champ
Family: Rubiaceae
Common Name: Over the Mountain Dragon
Morphological Characteristics:
This is a perennial climbing herb. The roots are typically yellow or red, with a reddish or pale red cross-section. The stems have four edges and are covered with small barbs along the ridges. The leaves are usually four-lobed, long-stalked, and nearly triangular-ovate in shape, measuring 2–6 cm in length and 1–4 cm in width. They have five prominent basal veins. The flowers are small and arranged in conical cymes, with a pale yellow corolla that has five lobes. There are five stamens, inserted into the throat of the corolla tube. The ovary is inferior, divided into two chambers, and the style is two-lobed. The fruit is spherical and turns blue-black when cooked.
Flowering occurs from September to October, and the fruits mature in November.
Habitat and Distribution:
It is primarily found in tropical and subtropical regions, with some species extending into temperate zones. It commonly grows in mixed forests, shrubs, along roadsides, in gullies, and on hillside grasslands.
This plant is widespread across the county, particularly in areas with long-painted East swords and high mountain ranges.
Medicinal Parts:
The dried roots are known as "Barnyardgrass," while the dried stems are referred to as "Shanlong."
Taste:
Bitter and cold in nature. It helps cool the blood and stop bleeding when charred, and it also promotes blood circulation and removes stasis when used raw.
Indications:
It is used for various types of bleeding, irregular menstruation, bruises, and rheumatism.
Application References:
1. For various types of bleeding: Take 6–9 grams of herbal charcoal with water.
2. For amenorrhea and irregular menstruation: Use 30–45 grams of Valerian root with Jianshui feet, taken three times daily.
3. For rheumatism and bruises: Take 120 grams of Valerian root, steeped in 750 ml of water for seven days. Each serving is 30 ml, twice daily.
Recently, Zhu Hua, a young botanist at the Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences, discovered over 50 new species within the Rubiaceae family.
According to reports, the Rubiaceae family is a large group of flowering plants, consisting of about 450–500 genera and 6,000–7,000 species. In China, there are approximately 70 genera and 450 species. This family includes many economically important plants, such as medicinal herbs like cinchona and barnyardgrass, beverages like coffee, and ornamental plants like June snow and wolfberry. Zhu Hua's discoveries have significantly enhanced scientific understanding of the Rubiaceae family and laid the foundation for future research and utilization.
Most of the newly discovered species were published in SCI-indexed journals. For example, a new species of the genus Sphagnum in Thailand was published in the Nordic Journal of Botany, while new species found in Vietnam and Malaysia were published in Blumea, an international journal focused on plant taxonomy and biogeography. Additionally, Zhu Hua contributed to the monograph “The Taxonomic Study of the Chinese Yucagrass Rumex Plants,†published in the prestigious journal “Systematics and Plant Geography.†His work earned him recognition as an expert in the classification of this genus and led to an invitation from the Netherlands National Science Foundation to participate in an international project titled “The Taxonomic Study on the Plants of the Phyllostachys Branches†in Malaysia.
