A method for producing non-toxic sulfur is provided to produce non-toxic sulfur at low cost by mixing radish juice, pine needle juice, Aralia elata juice, persimmon vinegar, calcium carbonate, acetic acid and sulfur water. A method for producing non-toxic sulfur comprises the following steps of: heating sulfur at 100°C~150°C for 30~50 minutes(S10); dissolving 100~200g of heated sulfur in 1 litter of water to obtain sulfur water(S20); mixing 41~60wt% of sulfur water, 15~25wt% of radish juice, 9~17wt% of pine needle juice, 8~12wt% of Aralia elata juice and 4~5wt% of persimmon vinegar to prepare a first mixed liquid(S30); aging 96~97wt% of the first mixed liquid and 3~4wt% of calcium carbonate at 120°C~180°C for 2~3 hours to prepare a second mixed liquid(S40); mixing 98~99wt% of the second mixed liquid and 1~2wt% of acetic acid to prepare a third mixed liquid(S50); heating the third mixed liquid at 60~80°C for 2~3 hours(S60); and standing the third mixed liquid at room temperature for 24 hours or more and cooling and precipitating the third mixed liquid(S70).
