What Is Jin Yin Hua (Flos Lonicerae)

Jin Yin Hua also known as Flos Lonicerae is the flower bud and early flower of honeysuckle. It is a relatively practical and common Chinese herbal medicine, which first appeared in <Mingyi Bie Lu> around 420-589 AD.

Honeysuckle commonly known as Lonicera is a semi-evergreen shrub of the Caprifoliaceae family. There are about 180 species of this genus, which are distributed in temperate and subtropical regions of North America, Europe, Asia and Northern Africa. Most of them are for ornamental use, and only some plants have medicinal value.

The Jin Yin Hua referred to herein is the flower bud and early flower of Lonicera japonica, Lonicera hypoglauca, Lonicera confuse, or Lonicera dasystyla.

Lonicera japonica is highly adaptable and often grows in shrubs or sparse forests below 1,500 meters above sea level. It can be found in China, Japan, North Korea, and North America.

Lonicera hypoglauca often grows in shrubs or sparse forests at an altitude of 200-700 meters. It is distributed in Anhui, Zhejiang, Jiangxi, Fujian, Hunan and Hubei provinces in China.

In the early summer of each year, people gather the flower buds and flowers of Honeysuckle, remove their impurities, dry them in the shade, and make them into Chinese herbs.

Jin Yin Hua contains chlorogenic acid, isochlorogenic acid, caffeic acid, luteolin, flavonoids, triterpenoid saponins, iridoid glycosides, and volatile oil. The Light-colored Jin Yin Hua with fresh fragrance is the best.
