The quality of Chinese herbs significantly affects their therapeutic efficacy and safety. In TCM, the concept of "Dao Di Yao Cai" (authentic regional herbs) recognises that the same plant species grown in different regions can have substantially different potency — much like terroir in winemaking. Historically, each herb has an ideal growing region: Huang Qi from Shanxi province, Dang Gui from Gansu province, Chuan Xiong from Sichuan, and Di Huang from Henan (historically called Huai Qing Fu, giving rise to the term "Huai" herbs for the four famous herbs from this region).

Modern quality concerns extend beyond regional authenticity to include: pesticide residues (herbs grown with excessive agricultural chemicals), heavy metal contamination (particularly lead, mercury, arsenic, and cadmium from polluted soils), sulphur dioxide fumigation (used to improve appearance and prevent insect damage, but potentially harmful), microbial contamination, and adulteration or substitution (cheaper species substituted for expensive ones). Responsible practitioners source from suppliers who conduct laboratory testing and can provide certificates of analysis.

In Australia, Chinese herbal medicines are regulated by the Therapeutic Goods Administration (TGA). Registered and listed products must meet quality standards. When practitioners prepare custom prescriptions, they should use herbs from Australian-approved suppliers who comply with import regulations and testing requirements. Patients can support quality by choosing registered practitioners who source responsibly, asking about their supplier's testing practices, and being cautious about purchasing herbs online from unverified sources. Good quality herbs — while sometimes more expensive — deliver better clinical results and greater safety.
