The Ibans of Rumah Aling believe that wearing a special charm made from this seed(buah kikau)will stop a child from biting his/her nails.
The older generation (now in their 60's) would all wear them.
Today fewer children wear them because their own parents have forgotten about this special charm.
Whenever an elder finds a tree (akak) full of these seeds she will collect them and dry them carefully. A long string of the seeds can be hung in the kitchen or backyard for over a few years and the seeds would become hard as wood.
Anyone who would like to have some can contact Madam Pantan in Rh. Aling . She would be only too happy to give you some. Pl. write to her : Madam Pantan Jiram
