Terp sauce is a cannabis concentrate that contains high levels of terpenes, which are the aromatic oils that give cannabis strains their scent. Their more technical name is “high terpene full spectrum extracts,” or HTFSEs. Not only are terpenes responsible for the sweet, earthy, and sour aromas found in cannabis, they are also thought to influence the overall effect of each strain. In other words, terpenes might contribute to the many effects associated with cannabis such as feeling relaxed, uplifted, focused, or stress-free. Terp sauce is a type of cannabis extract that concentrates these terpenes in a liquid, runny “sauce” that is usually vaporized or dabbed. 
Many different variations of terp sauce exist. Liquid terpene extracts may be combined with solid THCA or CBD isolate, or mixed with a potent distillate. It may fall somewhere in between, forming a soft, wax-like sugar. The common characteristic of terp sauces is that they are terpene-rich preparations, containing higher-than-average levels of terpenes. A terp sauce may, for example, contain 30% cannabinoids like THC and CBD, while the remaining 70% of the product is terpene extract.
