'Veins’: This refers to fiber bundles or vascular bundles in the medicinal material. After the medicinal material is broken, its fiber bundles or vascular bundles present as uneven filaments that look similar to the tendons and vessels of the human body, thus they are called veins. When they appear in an orderly arrangement on the cut surface of the medicinal material, little dotted marks can be seen that are called ‘vein dots’. Relatively large marks from vascular bundles are also called ‘vein striations’. |
