Both ''Dracaena'' and '' Calamus'' resins are still often marketed today as dragon's blood, with little or no distinction being made between the plant sources; however, the resin obtained from ''Calamus'' has become the most commonly sold type in modern times, often in the form of large balls of resin.

Visual characteristics

In his study of artists' pigments, the chemist George Field described dragon's blood as “a warm semi-transparent, rather dull, red colour, which is deepened by impure air, and darkened by light.”

. Dragon's blood incense is also occasionally sold as "red rock opium" to unsuspecting would-be drug buyers. It actually contains no opiates, and has only slight psychoactive effects, if any at all. Thaspine from the Dragon's Blood of the species '' Croton lechleri'' has possible use as a cancer drug. Today, dragon's blood from a South American plant can be bought in health food stores. Painters used of dragon's blood in the creation of flesh tones during the 17th century. By the 19th century, publications on artists' materials indicate that it was most useful as a varnish, not as pigment for painting. In 1835, George Field stated that dragon's blood is “unsatisfactory for painting.” However, the pigment was used to prepare the color known as "Chinese orange." Today, dragon's blood has a variety of uses. Outside of it being a pigment in paintings and colors, it is still used as a varnish for violins, in photoengraving, as a medicine, as an incense resin, and as a body oil. The occurrence of bitter taste masking compounds in dragon's blood from ''Daemonorops draco'' indicates the relevance of the species for use in food, beverage, and pharmaceutical industries.S.
