Visnaga daucoides is a species of flowering plant in the carrot family known by many common names, including toothpick-plant,[1] toothpickweed,[2] bisnaga, khella, or sometimes bishop's weed.

The leaves are up to 20 centimeters (7.9 in) long and generally oval to triangular in shape but dissected into many small linear to lance-shaped segments.

[7] Laboratory rat studies show that the extract slows the buildup of calcium oxalate crystals in the kidneys and acts as a diuretic.

Khellin, a chemical compound obtained from Visnaga daucoides, was used at one time as a smooth muscle relaxant, but its use is now limited due to adverse side effects.

[medical citation needed] Visnagin is another chemical compound found in Visnaga daucoides, which is toxic if ingested in the pure state.
