Gummo-oleoresins (oleo-gum resins, gum resins) occur mostly as crude balsams and contain also water-soluble gums. Processing of oleoresins is conducted on a large scale, especially in China (400,000 tons per year in the 1990s), but the technology is too labor-intensive to be viable in countries with high labor costs, such as the US.
Such turpentine is called gum turpentine. [11] The term gum turpentine may also refer to crude turpentine, which may cause some confusion. Turpentine may alternatively be extracted from destructive distillation of pine wood, [ 3 ] such as shredded pine stumps, roots, and slash, using the light end of the heavy naphtha fraction (boiling between ...

Myrrh is harvested by repeatedly wounding the trees to bleed the gum, which is waxy and coagulates quickly. After the harvest, the gum becomes hard and glossy. The gum is yellowish and may be either clear or opaque. It darkens deeply as it ages, and white streaks emerge. [3] Myrrh gum is commonly harvested from trees of the genus Commiphara.
Asafoetida has a pungent smell, as reflected in its name, lending it the common name of "stinking gum". The odour dissipates upon cooking; in cooked dishes, it delivers a smooth flavour reminiscent of leeks or other onion relatives. Asafoetida is also known colloquially as "devil's dung" in English (and similar expressions in many other languages).
