Medicinal Uses

Ophthalmic The fresh juice of the leaves is ophthalmic. Applied to the eyes it has a mildly irritating effect that increases blood flow tot he area, helping to strengthen resistance and clear away infections[254]. One or two drops put into the eyes is said to be of use in removing cataracts and also in the treatment of conjunctivitis[4, 61, 100, 254]. This remedy should only be used under the supervision of a trained practitioner[254]. The plant contains pyrrolizidine alkaloids which are highly toxic to the liver so the plant should not be used internally[254].
