The yellow variety is said to be particularly good for the skin and eyes. Since manjal karisalankanni is said to impart a golden hue to the skin, it has been referred to in the Siddha texts as pottralai kaiyanthakarai. They are platable. Eating a few neem leaves and a plant of kizhanelli, (Phyllanthus amarus) including its roots, along with manjal karisalankanni and karun thulasi everyday is said to be a protection against jaundice, anaemia and pitta disorders.
