Abstract
Zanthoxylum bungeanum Maxim. has been included in "The Plant List" (http://www.theplantlist.org) is a plant of the Rutaceae family of Zanthoxylum bungeanum, also named Chinese prickly ash. It is a resource for both medicinal and edible reasons. Traditional Chinese medicine claims that its main functions are: warming, and easing pain, destroying insects and soothing itching. Modern study has established that it possesses anti-inflammatory, antibacterial, insecticidal, anti-tumor, and other pharmacological characteristics effect. As a traditional condiment, Chinese prickly ash is the soul of Sichuan cuisine. Its numb flavor is the main characteristic and one crucial indicator of its quality. Studies have proven that the numb flavor of Chinese prickly ash stems from its abundant volatile oil. The research on the exact components of its volatile oil is becoming a hot spot. Sichuan, the central core-producing area of Chinese prickly ash, cultivates numerous species of prickly ash and is rich in resources. By planting Chinese prickly ash, the income level of local farmers has been enhanced, the villagers' quality of life has been considerably improved, and poverty has been lifted. This study briefly explains the planting status and production area distribution of prickly ash in Sichuan Province and reviews the recent research on the chemical components, volatile oil extraction methods, pharmacological effects, etc. Reasonable development prospects are projected to reference the in-depth research of prickly ash, the development and usage of resources, and the development of associated items.
