In Unani terminology, Panwad is the traditional name for Cassia tora.
It is commonly used as an anti-helminthic and mild purgative herb.
In Unani, Panwad is synonymously called Tira Tezak.
Khilaf Balakhi, Kiram Shab Tab, and Qalb are unrelated terms in this context — they refer to other conditions or concepts.
So, the correct answer is Tira Tezak.
