Aromatherapy : 
Aromatherapy is a form of alternative medicine that uses volatile plant materials, known as essential oils, and other aromatic compounds for the purpose of altering a person's mind, mood, cognitive function or health. Some essential oils such as tea tree[1] have demonstrated anti-microbial effects, but there is still a lack of clinical evidence demonstrating efficacy against bacterial, fungal, or viral infections. Evidence for the efficacy of aromatherapy in treating medical conditions remains poor, with a particular lack of studies employing rigorous methodology, however some evidence exists that essential oils may have therapeutic potential.
Ayurveda : (Sanskrit: आयुर्वेद; Āyurveda, "the complete knowledge for long life"; /ˌaɪ.ərˈveɪdə/) or ayurvedic medicine is a system of traditional medicine native to India and a form of alternative medicine. In Sanskrit, words āyus, meaning "longevity", and veda, meaning "related to knowledge" or "science". The earliest literature on Indian medical practice appeared during the Vedic period in India, i.e., in the mid-second millennium BCE. The Suśruta Saṃhitā and the Caraka Saṃhitā are encyclopedias of medicine compiled from various sources from the mid-first millennium BCE to about 500 CE. They are among the foundational works of Ayurveda. Over the following centuries, ayurvedic practitioners developed a number of medicinal preparations and surgical procedures for the treatment of various ailments .
SALT LAMPS : More recently, large crystal rocks are also used as Salt lamps. A salt lamp is a lamp carved from a larger salt crystal, often colored, with an incandescent bulb or a candle inside. The lamps give an attractive glow and are suitable for use as nightlights or for ambient mood lighting
