Identification  : Transverse section of leaf: The upper epidermal cells relatively large, tangentially elongated, the outer walls thickened and the inner walls mucilaginous, frequently swollen into semi circle. The lower epidermal cells smaller, occasionally having mucilage cells, the upper and lower epidermis bearing unicellular non-glandular hairs. 32 - 240µm long, 24 - 32µm in diameter with short cuticle striations. Palisade cells 2 - 3 rows, spongy cells, subcircular, containing cluster of calcium oxalate, 11 - 40µm in diameter. Midrib bundles collateral, the inner side of the upper and lower epidermis having 1 - 2 layers of collenchymatous cells.

Processing  : Eliminate foreign matter, wash, cut into pieces and dry.

Action  : To remove toxic heat, to reduce heat from blood, and to induce subsidence of swelling.
