Chemical composition and biological activities of Lonicera caprifolium L. (Caprifoliaceae) essential oil

This work aimed to investigate the chemical composition, antioxidant activity, antinociceptive effect, and wound healing activity of the Lonicera caprifolium L. flower essential oil (LCEO). Linalool (16.42%), d-limonene (9.99%), and α-cadinol (10.65%) were the most prevalent components of the LCEO. The LCEO revealed moderate DPPH and ABTS radical-scavenging activity. LCEO exhibited potent antinociceptive activity in acetic acid-induced writhing and hot plate-induced pain model; LCEO reduced 73.88 ± 2.78% of writhing and significantly increased pain withdrawal latency in the mice, respectively. The LCEO also presented a potent wound healing effect, with 98.08 ± 1.37% wound closure on the 12th day of treatment. The results of the study demonstrate antioxidant and wound healing potential with antinociceptive effect. To the best of our knowledge, this is the first report on the bioactivities of L. caprifolium L. essential oil.

Ethnomedicinal plants used for snakebite in India: a brief overview

The result of human interface and assortment of the most desirable, influential, and successful plant species found in the immediate environment at a precise circumstance is attributable to indigenous knowledge of plant species. India has a rich variety of medicinal plants growing under different geographical and ecological conditions; 1500 out of 15,000 privileged plant species have been reported to have medicinal uses. Snakebite is a severe medical, social, and economic problem in many parts of the world, chiefly in tropical and subtropical nations where majority of the world's dangerous snakes are found and where access to treatment is limited. In India, a range of medicinal plants are used as antidotes for snakebites, used either singly or in combination with other agents. The present study makes an effort to assemble information on medicinal plants that are grown and used for snakebite treatment in India. From a range of literature sources, data have been compiled with emphasis on the plants, family, parts used, etc., depending on the availability of information. This paper enumerates 523 plant species belonging to 122 families that act as antidotes against snakebites. We believe this study of herbal antidotes against snake venom is of substantial significance to society.
