Picrorhiza kurroa Royle ex Benth is one of the most important medicinal plants, commonly used in traditional medicinal systems. The plant has several medicinal properties due to the presence of bio active components viz., Picroside I and Picroside II, cucurbitacins and phenolic components. These chemical compounds are found in the roots and rhizomes of this herb, and are used to cure various ailments such as liver problems, spleen disorder, fever and asthma. World annual demand of P. kurroa is 500 tons per year while production is 375 tons (Thani et al., 2018). It has become endangered in various regions due to indiscriminate exploitation for medicinal purposes. Immediate steps need to be taken for the conservation of this medicinal herb otherwise it will lead to extinction. This paper gives an overview of geographic distribution, taxonomic feature, agrotechnology, phyto-chemistry, molecular studies, and conservation of P. kurroa.

Picthorhiza kurroa Royle ex Benth是最重要的药用植物之一，通常在传统药用系统中使用。由于存在生物活性成分，即Picroside I和Picroside II，葫芦素和酚类成分，该植物具有多种药用特性。这些化合物存在于这种草药的根和根茎中，用于治疗各种疾病，例如肝脏问题，脾脏疾病，发烧和哮喘。世界对库尔罗埃亚的年度需求每年500吨，而产量375吨（Thani等人，2018）。由于出于药物目的的不加选择的剥削，它已在各个地区受到威胁。需要立即采取措施来保存这种药草，否则将导致灭绝。本文概述了P. kurroa的地理分布，分类学特征，农业技术，植物化学，分子研究和保护。
