The term 'Soothing Juice' can be solved by the four-letter word 'Aloe'. Aloe is a succulent plant that has been used for centuries for its medicinal properties. The juice extracted from the leaves of the aloe plant is known to have a soothing effect on the skin and can be used to treat sunburns, rashes, and other skin irritations. It is also believed to have anti-inflammatory and antioxidant properties.
