Beautifully Powerful

With fragrant sprays of creamy white flowers, Japanese honeysuckle (Lonicera japonica) is a beautiful medicinal plant with a long history of use. While often considered an invasive weed, it provides many health benefits and is an important herb in Traditional Chinese Medicine (TCM). According to TCM, honeysuckle “clears heat and relieves toxicity.” It also helps to calm inflammation and is used for viral and bacterial infections. With over 140 active medicinal compounds, Japanese honeysuckle is anti-inflammatory, antibacterial, antiviral, anti oxidative, and hepatoprotective. Wow!

A study published in PLoS One found that an extract of Lonicera japonica berries helped to modulate the immune system and significantly increased killer (NK) cells, which are known to destroy viruses and tumor cells within the body. Japanese honeysuckle also reduces blood sugar levels in diabetic patients and has excellent anti-inflammatory properties. It may help ease depression as well. Researchers found that a polysaccharide extracted from the plant “exhibited a strong protective effect on mice with depression by inhibiting NLRP3 inflammasome.”

Edible and Medicinal Uses of Japanese Honeysuckle

One of several edible varieties of honeysuckle, Lonicera japonica flowers can be used to flavor jellies, syrups, baked goods, sorbet, and ice cream. They also make a lovely iced tea that’s perfect for hot summer days. Or add Japanese honeysuckle syrup to sparkling water for a refreshing spritzer. It’s easy to be creative with this plant! Additionally, you can cook the leaves and enjoy them as a vegetable.

Medicinally, a glycerite made from the flowers is an excellent sore throat remedy, while an infusion using the stems and flowers is used for viral infections, upper respiratory tract infections, and dysentery. Moreover, an infusion made from the flowers is often used to address skin diseases, colds, pain, and swelling. You can use the infusion externally as a wash for acne, skin inflammations, rashes, and sores. Extracts of the flower also lower blood cholesterol. What’s more, the antimicrobial properties of the plant are effective against staph, strep, cholera, meningitis, tuberculosis, and e.coli.


Japanese honeysuckle leaves contain saponins, which are toxic but poorly absorbed by the human body and generally pass through without harm. However, make sure to cook the leaves thoroughly and change the water at least once to remove most of the saponins to avoid any potential issues. Fresh Lonicera japonica berries are not edible. Honeysuckle can slow blood clotting. Do not use it for two weeks before a scheduled surgery.
