Rose petal perfume can be made by layering rose petals and salt in an airtight container, then adding alcohol and letting it marinate for days. Stirring occasionally extracts the rose scent into the alcohol. The result is a pleasant rose scent that fills the home. Rose water can also be made by infusing rose petals in boiling water for a few minutes, then filtering the water, which has astringent and tonic properties. The rose water can be applied to cotton balls and placed on the eyes for 10 minutes each morning to benefit the skin.
