A: The criteria for selecting quality lingzhi are :
1) Species
-A good specie with higher active components will ensure greater efficacy.
2) Growing environment
-Lingzhi is a highly absorbent plant. Thus, it's important that it is grown in a clean environment, free from contaminants and pollutants.
3) Age
-Different species of Lingzhi have different maturity period. However, it is important that the harvest time is made when the effective components are the richest. Hence, the timing of the harvest is very important.
4) Processing method
-Different components in the Lingzhi can only be extracted using diffrent medium, and at differing temperature. As such, good quality Lingzhi is one that is extracted using multiple medium and differing temperature.
5)Endorsement by relevant authorities
-Last but not least, a good quality Lingzhi should have endorsements from Goverment and Health authorities.
