Spilanthol (affinin) is a fatty acid amide isolated from Acmella oleracea. [1] It is believed to be responsible for the local anesthetic properties of the plant. [2]Spilanthol permeates the human skin [3] and the inside lining of the cheeks in the mouth (buccal mucosa), [4] resulting in local as well as systemic pharmacological concentrations.
The spilanthol proved effective at killing mosquitoes, with a 24-hour LD 100 of 12.5 μg/mL, and 50% mortality at 6.25 μg/mL. The mixture of spilanthol isomers produced a 66% weight reduction of corn earworm larvae at 250 μg/mL after 6 days. [18]
The best known of these is the toothache plant, which was formerly Spilanthes acmella but is now considered part of its own genus and is referred to as Acmella oleracea. [7] Other taxa formerly included in Spilanthes include: [3] Adenostemma; Eclipta; Heliopsis; Isocarpha; Jaegeria; Melampodium; Salmea; Verbesina; Wollastonia; Zinnia

Kalanchoe daigremontiana, formerly known as Bryophyllum daigremontianum and commonly called mother of thousands, alligator plant or Mexican hat plant, is a succulent plant native to Madagascar. Like other members of Bryophyllum (now included in the genus Kalanchoe ), [ 1 ] it can propagate vegetatively from plantlets that develop on its leaf ...
This plant genus is known to have active aristolochic acids, which pipevine swallowtail larvae sequester and use for defensive properties. [ 14 ] A common host plant is the Virginia snakeroot , ( Aristolochia serpentaria ), which can be found in the Eastern United States and in Florida.
Peperomia pellucida (also known by common names pepper elder, shining bush plant, crab claw herb, and man to man) is an annual, shallow-rooted herb, usually growing to a height of about 15 to 45 cm (6 to 18 inches), it is characterized by succulent stems, shiny, heart-shaped, fleshy leaves and tiny, dot-like seeds attached to several fruiting spikes.
