Halyon, botanically classified as Lepidium sativum and widely known as Garden Cress or Chandrashoor, consists of tiny, oval, reddish-brown seeds harvested from an annual fast-growing herb of the Brassicaceae family. In Unani and Greco-Arabic medicine, Halyon holds an authoritative rank among the warming restorative remedies and is classified as having a Hot and Dry (Garm-o-Khushk, 3rd degree) temperament. Highly celebrated for its penetrating heat, resolvent (Muhallil) virtues, and rich mucilaginous outer layer, Halyon is the classical remedy of choice for dissolving cold phlegmatic humors (Balgham), dispelling deep-seated pelvic stagnation, stimulating healthy uterine flow, restoring low hemoglobin, and reinforcing weakened lumbar vertebrae
