Overview of Mullein Plant Source, Distribution, and Growing Environment

Mullein (scientific name: Salvia miltiorrhiza), also known as Danshen or red sage, is a perennial herb belonging to the Lamiaceae family. Below is an overview of its plant source, distribution, and growth environment:

  1. Plant Source:
    Mullein is native to China and is one of the traditional Chinese medicinal herbs. Its roots and stems have medicinal value, serving as important ingredient in Chinese medicine formulations and health products. Due to its medicinal and economic value, mullein is widely cultivated.
  2. Distribution:
    Mullein is primarily found in the Yangtze River basin and southern regions of China, including Shaanxi, Gansu, Henan, Hebei, Shanxi, Hubei, Hunan, Sichuan, Jiangsu, Zhejiang, Anhui, Shandong, Guangdong, and Guangxi. Given suitable climate and soil conditions, it can also grow and reproduce in other regions.
  3. Growth Environment:
    Mullein thrives in warm, humid environments, with an ideal growth temperature of 15℃ to 25℃. It requires ample sunlight but can also adapt to semi-shaded conditions. While its soil requirements are not strict, it prefers loose, fertile, well-drained loamy soils. A pH level that is neutral to slightly alkaline is more conducive for its growth.
