Safety Overview
1.Trichosanthes — Overview
Trichosanthes kirilowii, commonly known as Trichosanthes Med, Gualou (in Chinese), or Hanultari (in Korean), is a robust perennial herbaceous liana belonging to the Cucurbitaceae family. This vigorous vine can reach impressive heights of up to 10 meters, utilizing axillary tendrils to climb surrounding vegetation. Its leaves are distinctively large, typically nearly round or cordate, lobate, and covered with soft hairs, measuring up to 20 cm in length. The stems are multi-branched and also feature soft, white hairs.
From May to August, the plant produces striking unisexual flowers with a white, bell-shaped corolla featuring a beautifully fringed apex, each up to 5 cm in diameter. Following flowering, the vine develops nearly spherical fruits that mature from August through October, transforming from green to a vibrant orange-yellow hue, often resembling small gourds. The roots are cylindrical and fawn-colored, serving as a primary medicinal part. Native to East Asia, particularly widespread in China, Korea, and Japan, Trichosanthes kirilowii thrives in warm, moist habitats with well-drained sandy soil.
It is commonly found in forests, grasslands, and hillsides, and is extensively cultivated in Chinese provinces like Henan and Shandong for its significant medicinal uses. The genus Trichosanthes encompasses approximately 84 plant varieties globally, with 34 species and 6 variants found in China, underscoring its botanical diversity and importance within the gourd family.
