Paris polyphylla, also known as Qiyeyizhihua, Huachonglou, Qiyelian, Tiedengtai, etc., is the dried rhizome of Paris polyphylla var. yunnanensis or Paris polyphylla of the genus Paris in the family Liliaceae. It is a precious traditional Chinese medicinal herb with the effects of clearing heat and detoxifying, reducing swelling and relieving pain, and cooling the liver to calm fright. Let's take a look at the origin distribution of Paris polyphylla below!
Origin Distribution of Paris polyphylla
The origins of Paris polyphylla var. yunnanensis are mainly distributed in Yunnan, Guizhou, Sichuan and other places, while the origins of Paris polyphylla are mainly distributed in Guangdong, Guangxi, Jiangxi, Fujian, Shaanxi, Sichuan and other places.
Origin Environment of Paris polyphylla
1. Soil: Paris polyphylla grows best in slightly acidic humus soil or fertile sandy soil with good water permeability. It cannot grow in alkaline soil or clay soil, and soil that is sticky, prone to water accumulation and hardened is not suitable for growth.
2. Water: Paris polyphylla prefers a cool, shady and moist environment with moderate moisture. It is afraid of both drought and water accumulation. If the soil moisture content is too low, it is easy to cause the stems and leaves to lose water and the root system to dry up and die, while if it is too high, it is prone to pests, diseases and rhizome rot.
3. Temperature: Paris polyphylla plants are relatively cold-tolerant and suffer no frost damage at low temperatures. From late February to early March, it can sprout and grow at a temperature of 5°C, and even at a minimum temperature of 2°C. At a temperature of 1-2°C, no frost damage occurs to the buds. Generally, the suitable temperature for seed germination, root growth and development, and terminal bud germination is 18°C-20°C, for seedling emergence it is 20°C, for aboveground plant growth it is 16°C-20°C, and for underground rhizome growth it is 14°C-18°C.
4. Light: Paris polyphylla is a shade-loving plant that prefers slanting or diffused light and avoids direct strong light. Its growth requires a shaded environment. Strong light will cause the leaves to wither. Generally, the seed germination and seedling stages require better shading, while two years before maturity, shading should be appropriately reduced and light increased, which is beneficial to the accumulation of secondary metabolites and dry matter.
