Four Substances Tang is a classic blood tonic. Its basic formula consists of 12 grams of Radix Rehmanniae Praeparata, 9 grams of Radix Angelicae Sinensis, 9 grams of Radix Paeoniae Alba, and 6 grams of Rhizoma Ligustici Chuanxiong, and the herbs need to be cleaned briefly and then soaked in water for about 30 minutes prior to brewing.
When simmering, the herbs should be decocted quickly over a high heat, then boiled over a low heat for 20-30 minutes, and then the simmering broth should be poured out and added to water and simmered again for about 30 minutes.
The two boiled medicinal broth should be mixed and divided into 2-3 portions, which can be taken twice in the morning and evening, or three times in the morning, midday and evening.

If there is a need to add or subtract medicines, it is recommended to consult a physician and follow the doctor’s instructions for boiling and taking medicines.
