The herein-disclosed invention is a liquid, humectant composition comprising about 70%-88% distilled water, about 7%-14% food-grade USP propylene glycol, about 5%-10% ethanol, about 4%-8% raw honey, about 0.15%-0.16% Cascade hop oil, about 0.5%-0.9% citric acid, and about 0.06%-0.4% sodium benzoate. The composition should be prepared with USP, food-grade ingredients at room temperature, atmospheric pressure. Super-critical extraction of the Cascade hop oil ingredient is recommended.Once prepared, between 88.8 ml and 600 ml of said composition should be dropped onto a vented humidor disc for absorption: said saturated disc should then be placed with desired plant matter into a sealed plastic baggie, optionally inside a sealed humidor box. Said plant matter should reach an equilibrium humidity between 60 and 75% and should receive lasting preservative and aromatic effects.
