Female insect of Laccifer lacca (syn. Carteria lacca, Coccus lacca, Kerria lacca) produce the resinous stick-lac around the branches of certain trees.
A number of other species are used including Tachardia lacca, although the abovementioned species is primarily cultivated.
Typically collected from the trees of Ziziphus marutiana, Butea monosperma, Schleichera oleosa, Ficus religiosa, Mimosa spp. etc.
Parts used:
Secreted stick-lac which has been purified
Stick lac is the raw product; Seed Lac, Grain Seed Lac, Shellac, Button Lac and Sheet Lac are all names of the purified product after different processing.
Three main products on the market are as follows:
Temperature & Taste:
Warm, dry (some consider it Cool). Sweet, salty, bitter, astringent, slightly toxic
In TCM it is regarded as Neutral
Unani medicine regards unprocessed Lacca as Hot and Dry in the 3rd degree, but Hot and Dry in the 1st degree once prepared.
Constituents:
Resin (70–80%), proteins, sugars, pigments, anthraquinone, traces of essentail oil

Dose:
Powder: 500mg–3 grams, best taken with Honey, Milk or Ghee (Ayurveda)
Preparation:
As with other gums, it is softened or dissolved by boiling in water, then strained and decocted until as thick as syrup, then dried.
1. Prepared Lacca:
In Chinese sources, the Lacca is recommended to be dried, broken to cleanse admixture of sticks and insects, then powdered finely.
2. Purified Lacca: (Unani)
The raw Lacca can be heated by a lamp flame and the melted resin falls into a basin of hot water. The pure Lacca falls to the bottom, while waste products and impurities float. It is then removed, dried and kept for use.
3. Washed Lacca:
Lacca is cleansed of stick and admixture by hand, then powdered. Next Lemongrass and Rhubarb are decocted (1 part to 16 parts water, by weight), and decocted down to one-quarter and strained. The Lacca powder is ground with this decoction in a mortar for 6 hours, then strained through muslin cloth. The Lacca that doesnt pass through the cloth is ground again and strained. Once all has been strained, the decoction is left to settle in the refrigerator overnight, then the water is carefully poured off, and the Lacca is spread out and dried on trays.
Long Birthwort sometimes replaces Rhubarb (however, Rhubarb is better, and Birthwort is obsolete).
4. Boiled Lacca:
To prepare it is boiled in a decoction of herbs until dissolved, then strained, thickened, and pour onto trays to dry. Typical herbs used include i) Rhubarb; ii) Lemongrass and Rhubarb; iii) Birthwort and Lemongrass; iv) decoction of Hartwort and Fenugreek seed. This is best and was how it was formerly prepared in the West.
