Background: Nephrolithiasis is of the most prevalent urinary tract disease. It seems worthwhile to replace the conventional treatments with more beneficial and safer agents, particularly herbal medicines which are receiving an increasing interest nowadays. Aims: In this study, we investigated the protective and curative effects of Achillea millefolium L. on ethylene glycol (EG)-induced nephrolithiasis in rats. Materials and Methods: The extract of A. millefolium was prepared by soxhlet method. Forty male Wistar rats were randomly divided into five groups (N = 8) as follows. The negative control (group A) received tap drinking water. Rats in sham (positive control group B), curative (group C and D), and preventive (group E) groups all received 1% EG in drinking water according to the experimental protocol for 30 days. In the curative groups, dosages of 200 and 400 mg/kg body weight (BW) of A. millefolium extract were administered orally from day 15 to the end of the experiment, group C and D, respectively. Group E received 200 mg/kg A. millefolium extract from the 1 st day throughout the experiment. Urinary oxalate and citrate concentrations were measured by spectrophotometer on the first and 30 th days. On day 31, the kidneys were removed and examined histopathologically for counting the calcium oxalate (CaOx) deposits in 50 microscopic fields. Results: In the curative and preventive groups, administration of A. millefolium extract showed significant reduction in urinary oxalate concentration (P < 0.05). Also, urinary citrate concentration was significantly increased in group C, D, and E. The CaOx deposits significantly decreased in group C to E compared with the group B. Conclusions: According to our results, A. millefolium extract had preventive and curative effects on EG-induced renal calculi.
