I. Raw Material Selection
Aromatic Herbs: High-quality natural aromatic herbs are crucial. Commonly used ones include sandalwood, agarwood, rosewood, and various dried flower petals. These materials are carefully selected to ensure their purity and fragrance intensity. For example, sandalwood should have a rich, mellow scent, and the agarwood pieces need to be of good quality to emit a long-lasting and elegant fragrance.
