👉 Complimentary fumes refer to the natural, often pleasant odors released by certain plants, flowers, and herbs when they release moisture into the air, even without water. These fumes are a result of the plant's transpiration process, where water evaporates from the leaves, carrying with it volatile organic compounds that can have a fragrant, sometimes sweet or earthy scent. This phenomenon not only adds to the aesthetic appeal of a garden or indoor space but also has potential benefits for human well-being, such as reducing stress and enhancing mood, thanks to the calming and uplifting effects of these natural aromas.
