The aerial parts of A. ilicifolius are used as a poultice on wounds, and together with ginger, they are ground and put on sore legs, while a porridge from them is taken for bowel complaints. In Indonesia, a poultice of the leaves may be applied to treat rheumatic pain, or as an emollient. In Thailand, the stem and leaves are also used to promote longevity. In Papua New Guinea the leaves, crushed in water, are drunk to facilitate delivery. The solution can also be drunk before an operation.
