Khushbu, meaning "fragrance" in Hindi and Urdu, refers to pleasant scents that can evoke emotions and memories. Fragrances are often derived from natural sources like flowers, spices, and herbs, and are used in perfumes, essential oils, and incense. They play a significant role in cultural practices, rituals, and personal grooming. In addition to their aesthetic appeal, fragrances can influence mood and well-being. Aromatherapy, for instance, utilizes specific scents to promote relaxation or energy. The study of fragrances also encompasses the science of olfaction, which explores how humans perceive and react to different smells.
