The peasants used it to treat fasciolosis (a parasitic disease caused by the liver fluke - Fasciola hepatica). The pharmacy began to buy oil from Ukrainian peasants and sold the purified oil as medicine at a price competitive with Italian oil.

Unfortunately, the local pharmacies were not interested in their raw material, as they preferred the Italian specification.
