What is the geographical distribution of this plant?
This plant is native to Europe, western Asia, and North Africa, but it has become widely naturalized across much of the temperate world. It frequently colonizes disturbed soils, roadsides, and waste areas throughout North America. Many populations can be found in various climates ranging from Mediterranean regions to more temperate zones. Its ability to thrive in diverse environments has allowed it to spread extensively across different continents. This widespread distribution is largely due to its adaptability to varied soil types and sunlight conditions.
How is this plant cultivated?
This plant requires full sun and well-drained, moderately fertile soil to thrive in most temperate climates.
It is a hardy perennial that can be grown from seed or by dividing established clumps in early spring. Once established, the species is quite drought-tolerant and can spread easily through self-seeding in favorable conditions. It prefers a location where it will not be overcrowded to ensure adequate air circulation around its stems.
Regular weeding helps prevent competition for nutrients during the initial growing stages.
What parts of this plant are used medicinally?
This plant Verbena officinalis is used medicinally through its aerial part, which includes the leaves and flowering stems. The herb is typically harvested in its entirety to ensure all active compounds are collected for preparations. Each leaf contains specific phytochemicals that contribute to its therapeutic properties in traditional remedies. Practitioners often dry the entire aerial part to create teas or tinctures for various ailments. This comprehensive use of the herb allows for a potent concentration of its natural healing components.
According to a study published by "Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica", the dried aerial part of Verbena officiinalis is used for the determination of ursolic acid. The HPLC method utilizes a Kromasil C18 column measuring 4.6 mm x 250 mm with a 5 microns stationary phase. The mobile phase consists of methanol and a sodium phosphate buffer made from 1.7997 g of monobasic sodium phosphate (MW = 119.98) and 1.02 mL of 85% phosphoric acid in a total volume of 1,000 mL. This process maintains a flow-rate of 0.8 mL per minute and a temperature of 40 degrees C using a DAD detector set at 210 nm. The liner range is 0.251-10.04 micrograms with an r = 1.0000. An average recovery of 98.1% was achieved with n = 6 and a RSD of 1.0%.
