Aspergillus flavus is a fungus that occurs in pesticides, soil, corn, peanuts, hay and animal organs. Aspergillus flavus has also been found in Chinese herbs such as corydalis (yan hu suo), cyperus (xiang fu) and jujube (da zao). It thrives especially in warm temperatures of 77–86°F, a relative humidity above 75% and a pH level above 5.6. The fungus can actually grow in temperatures as low as 54° but will not be toxic.

Strains of the fungi Aspergillus flavus and Aspergillus parasiticus produce aflatoxins. Researchers have determined that four kinds of aflatoxins are highly toxic and possibly carcinogenic; they have been classified into categories B1, B2, G1 and G2. To identify the type of aflatoxin, the sample is dissolved in chloroform. If the substance then exhibits a blue color when exposed under UV light, then it is either B1 or B2. If it exhibits a yellow-green color, then it is the G1 or G2 type.

Another mycotoxin, ochratoxin A, flourishes in temperatures around 77°F and a humidity level of 18.5%. Ochratoxin A has been detected in soil, milk, rice, grain, flour, yellow beans, peanuts, corn, coffee, grains, vegetables, herbs and animal feed. Ochratoxins thrive in inferior Chinese herbs stored in poor conditions. KP analyzes the herbs' raw materials for the volume of Ochratoxin A, to keep herbs from metabolizing ochratoxins and to guarantee the herbs' safety.

KP enforces strict international regulation standards. Aflatoxin and mycotoxin testing is performed on all herbs at risk of contamination. KP's values high-quality premium herbs and herbs that contain unacceptable aflatoxin and ochratoxin levels are discarded These strict standards keep herbs safe and efficacious for consumers.
