According to Sanskrit writers, new or recently exuded \*guggulu\* is moist, viscid, fragrant and of a golden colour. It burns in the fire, melts in the sun and forms a milky emulsion with hot water. Old \*guggulu\* is dry and without flavour or colour; it should not be used in medicine. - [Previous: c5.s8.t1.1](https://indike.org/pramana/ins.science.dutt-1877.c5.s8.t1.1) - [Next: c5.s8.t1.3](https://indike.org/pramana/ins.science.dutt-1877.c5.s8.t1.3) - [Up: c5.s8.t1](https://indike.org/pramana/ins.science.dutt-1877.c5.s8.t1) --- Source: [https://indike.org/pramana/ins.science.dutt-1877.c5.s8.t1.2](https://indike.org/pramana/ins.science.dutt-1877.c5.s8.t1.2) · Pramāṇa
