Classical names are descriptive, which makes them flexible, and flexibility is not what you want on a label. A pharmacopoeia exists to fix the definition.
The official definition
The Indian valerian is the official Tagara of the Indian Pharmacopoeia, and the material is defined as the dried rhizome and roots of Valeriana wallichii. Two things are fixed by that sentence: the species, and the part.
Why both halves matter
A species alone does not describe an ingredient, because different parts of one plant are different materials. Naming the rhizome and roots excludes the aerial parts. The same logic governs the rest of a careful label, and it is why the part collected is stated as carefully as the plant.
What it rules out
A pharmacopoeial definition is also a way of ruling out substitution. Where a classical name has been applied loosely to more than one plant, an official definition says which one counts.
On the jar
Tagara Capsules state Valeriana wallichii, root and rhizome, in a vegetarian capsule shell, and every batch is tested before release.
