Folk medicinal uses
The 'leaves' (stems) of tuna are used to make a decoction used 'to keep away inflammation inside'. The baked sliced stem is applied to swellings and bound on the head and put in the bed for vomiting and fever. For headaches the sliced stem is bound on the head and for soreness, pains and constipation it is rubbed with salt and applied as a poultice. The fruit is astringent. (8, I5, 26).
