Lianqiao is first recorded in the Shennong Bencao Jing, noted for its bitter taste and slightly cold nature. It enters the Lung, Heart, and Small Intestine meridians. It has functions of clearing heat and detoxifying, reducing swelling and dispersing nodules, and dispersing wind-heat. It is used for abscesses, scrofula, mastitis, erysipelas, and wind-heat colds. Its efficacy has been praised by physicians throughout history, with the Ming dynasty’s Li Shizhen calling Lianqiao the “sacred medicine for sores.” For centuries, Lianqiao has been a widely used and cost-effective medicinal material.
Lianqiao belongs to the Oleaceae family and blooms from March to April, with fruit ripening from July to September. The medicinal part is the dried fruit. In autumn, the fruit is harvested when it is initially ripe and still green, impurities are removed, steamed, and dried, known as “Green Lianqiao”; when the fruit is fully ripe, it is harvested, dried, and impurities removed, known as “Old Lianqiao”. The best quality is characterized by a yellow color, large petals, and thick shells. Lianqiao fruit is often combined with Jin Yin Hua (金银花, Honeysuckle) in medicinal preparations, such as “Wei C Yin Qiao Pian” and “Shuang Huang Lian Kou Fu Ye”, which exhibit broad-spectrum antibacterial effects. Jin Yin Hua can cool the blood and stop dysentery, showing a stronger inhibitory effect on typhoid bacilli than Lianqiao; Lianqiao can clear heart heat and has a better inhibitory effect on dysentery bacilli and influenza viruses than Jin Yin Hua.
Every part of Lianqiao is valuable; aside from its use in landscaping, its tender leaves can be made into Lianqiao tea. The health benefits of Lianqiao leaves are increasingly recognized, and modern pharmacological studies indicate that Lianqiao leaves have protective effects on the liver, anti-lipid oxidation, anti-aging, immune regulation, and enhanced stress resistance. The prospect of making tea from Lianqiao leaves is promising.
