Bala is a tropical mallow, native to India. It thrives best in zones 9 to 12. In Ayurvedic medicine, it is used for all three doshic imbalances. It is a tonic herb and is therefore used for strengthening conditions characterized by weakness, including nervous disorders. Since it contains ephedrine, bala is sometimes restricted and used only in ointments for massage. However, in Ayurvedic medicine, it is also used internally, though with proper attention to dosage.
