Mala is described as which entity in rasa vaha srotas?

• A. Pitta
• B. Poshaka Kapha
• C. Rakta
• D. Ama

Answer: (B)

Rasa vaha srotas is the channel that carries rasa dhatu and its associated by-products, and in this context the mala of rasa dhatu is described as the nourishing aspect of kapha—poshaka kapha. This reflects how kapha’s nourishing function supports tissue health and sustenance; the rasa mala isn’t treated as a waste toxin here, but as a sustaining factor that helps maintain rasa dhatu. Pitta and Rakta refer to other doshas/dhatus and don’t represent the nourishing by-product of this particular channel, while Ama denotes undigested toxin and isn’t the described mala in rasa vaha srotas. So the best fit is poshaka kapha.
