Anti-nociceptive and anti-inflammatory effects of the ethanolic extract of potato (Solanum tuberlosum)

The ethanol extract of potato tubers (Solanum tuberlosum L.) has been evaluated for antinociceptive and anti-inflammatory activities in mice. The acute treatment of mice with an ethanolic extract from the potato tuber at doses of 100 and 200 mg/kg, by oral administration, produced a significant anti-nociceptive effect in the acetic acid-induced writhing, formalin-induced pain licking and hot plate-induced pain. Also, the ethanolic extract of potato tubers significantly inhibited both carrageenan- and formalin-induced inflammation in mice as well as arachidonic acid-induced ear edema in mice. These inhibitions were statistically significant (p<0.05). These results provide support for the use of the ethanol extract of potato tuber in relieving inflammatory pain, and insight into the development of new agents for treating inflammatory diseases.
