INTRODUCTION Hemiscorpius lepturus envenomation is a serious health problem in the southern provinces of Iran. The antiserum produced in Iran to counteract this scorpion venom is not entirely effective due to the risk of anaphylactic shock and other adverse effects. METHODS Therefore, more efficient alternatives to treat patients deserve attention, and plants are extensively good candidates to be studied. This study aimed to assess the potential of the aqueous fraction of Malva sylvestris in inhibiting the toxic effects of H. lepturus venom. Injection of sub-lethal dose of H. lepturus venom leads to severe tissue damage in vital organs including the kidney, liver, heart and intestine, after 24 hours. RESULTS By injecting 80 mg of the aqueous extract of M. sylvestris into the peritoneum helped treat the damaged tissues caused by H. lepturus venom in mice. CONCLUSION Thus, Malva sylvestris could serve as an alternative treatment for scorpion sting envenomation and may be used as a drug to neutralize relevant toxic effects in patients stung by H. lepturus.
