Can Salvia miltiorrhiza be steeped in water for consumption?
Generally, Salvia miltiorrhiza (Danshen) can be steeped in water and consumed, but it should be used properly under the guidance of a traditional Chinese medicine practitioner. Detailed explanations are as follows:

As a commonly used traditional Chinese herb, drinking Danshen-infused water can, to some extent, promote blood circulation and alleviate discomfort caused by blood stasis, such as chest tightness and heart pain. However, the effect of consuming Danshen in this way is relatively mild, and the active ingredients in the herb may not fully dissolve into the water. Therefore, it is only suitable for mild symptoms or as an auxiliary health measure.
Excessive consumption of Danshen tea, however, may cause gastrointestinal discomfort symptoms such as nausea, vomiting, and abdominal pain. Therefore, it is recommended to consume it in moderation. Additionally, due to Danshen's blood-activating properties, individuals with a tendency to bleed, those undergoing anticoagulant therapy, or patients about to undergo surgery should avoid its use to prevent an increased risk of bleeding. Pregnant women should also avoid consuming Danshen to prevent potential adverse effects on the fetus and reduce the risk of miscarriage. Before using Danshen as a tea, it is advisable to consult a qualified physician or pharmacist to ensure safe and effective usage.
When preparing Danshen tea, attention should be paid to the dosage and steeping time to avoid excessive amounts or prolonged soaking, which may lead to reduced efficacy or adverse reactions.
