This oil is obtained by expression, or distillation, from the fresh rind of the fruit of Citrus Limetta. It is employed chiefly, if not exclusively, for the sake of its very agreeable odour; being mixed with substances used as liniment or ointment, in the same manner as oil of lemons. It has been asserted, however, to be of itself very efficacious in the itch. (Med. and Surg. Reporter, Oct. 1, 1864, p. 112).
