Acute toxicity and anti-inflammatory activity of an improved traditional medicine developed in Burkina Faso

Abstract

An Improved Traditional Medicine (ITM) in capsule form presented by traditional health practitioners in Burkina Faso as used for hepatoprotective and hepatocurative treatment for viral hepatitis B. The study's main objective was to investigate the anti-inflammatory properties of this ITM, which is used in treating viral hepatitis B in traditional medicine in Burkina Faso. Phytochemical screening revealed the presence of flavonoids, saponins, tannins, coumarins, alkaloids, sterols and triterpenes. The in vitro anti-inflammatory assay inhibited LOX by 15.69 ± 0.50% at a 100 µg/mL concentration. The LD50 was estimated to be greater than 5000 mg/kg. In vivo activity using the carrageenan anti-oedema test showed good dose-dependent anti-inflammatory activity of ITM at 30, 65 and 130 mg/kg bw. After 3 hours, the extract at various doses reduced edema to over 50% inhibition. After 5 h, oedema was reduced to 85.209% at the 130 mg/kg. However, the reference acetylsalicylic acid (ASA) at 100 mg/kg bw showed a percentage of 85.048% at 5 h. The IC50 obtained after the ABTS, FRAP and LPO antioxidant tests of the phytomedicine were 351.00 µg/mL, 353.20 mM EAA/L and 81.13%. However, the IC50 with the DPPH method was higher than 104 mg/mL. The phytomedicine would have anti-inflammatory and antioxidant properties due to the presence of bioactive phytochemicals on inflammation and free radicals.
