Solanum trilobatum also called as thoodhuvalai (Tamil: தூதுவளை) is an herb used to treat the common cold, cough and asthma. The herb can be consumed by mildly frying it in oil/ghee and then grinding it.
The plant is full of thorns, even the leaves have thorns, it is important to remove these thorns before cooking as the thorns are considered to be mildly toxic. The herb can be stored in powdered form, by drying the leaves under shade and making a powder out of it.
