Voucher Specimens & Scientific Traceability
Documented Authenticity from Source to Shipment
At Younis Aroma, scientific traceability is the foundation of our commitment to transparency, quality, and sustainability. Our voucher specimen system, developed in collaboration with Dr. Trish Flaster, ensures that every batch is botanically authenticated and fully documented from tree to shipment.
What Are Voucher Specimens?
Voucher specimens are pressed, preserved plant samples (leaves, stems, flowers) that serve as permanent, verifiable records of the exact species and origin for each batch. Each specimen is GPS-tagged, catalogued, and linked to collector records, providing scientific proof of authenticity and traceability.
