The occurrence of fire when taking Four Substances Tang is either an indication that one is not suffering from Blood deficiency and is not suitable for taking Four Substances Tang, or it is an indication that the Blood deficiency is intermingled with other problems, and one needs to choose the right medicine for the specific problem.
Si Wu Tang acts as a blood tonic.
If it is used for people with simple Blood deficiency, there will be no fire, and one needs to consider whether there is a case of misidentification.
Secondly, if it is not for those with simple Blood deficiency, such as Blood deficiency interspersed with phlegm-dampness, damp-heat, Blood stasis and other tangible real evils, it is not suitable to use Four Substances Tang alone. It is necessary to go for symptomatic compounding of some medicines according to the specific problems.
It is recommended to take Four Substances Tang under the guidance of a traditional Chinese medicine practitioner and not on one’s own.
