Medicinal Uses

Cancer Odontalgic A poultice of the heated root has been applied to the jaw to bring relief from toothache[257]. The plant has been used as a treatment for chickenpox[257]. The fruit of many members of this genus is a very rich source of vitamins and minerals, especially in vitamins A, C and E, flavanoids and other bio-active compounds. It is also a fairly good source of essential fatty acids, which is fairly unusual for a fruit. It is being investigated as a food that is capable of reducing the incidence of cancer and also as a means of halting or reversing the growth of cancers[214].
