Question:
Can you use the leaves of Valerian herb or just the roots?
Answers:
Roots, not leaves.
The chief constituent of Valerian is a yellowish-green to brownish-yellow oil which is present in the dried root varying from 0.5 to 2 per cent though an average yield rarely exceeds 0.8 per cent. This variation in quantity is partly explained by location: a dry, stony soil, yielding a root richer in oil than one that is moist and fertile.[3] The volatile oils that form the active ingredient are extremely pungent, somewhat reminiscent of well-matured cheese or wet dog. Valerian tea should not be prepared with boiling water, as this may drive off the lighter oils
