Introduction
Dendrobium and Salvia are common medicinal food substances. Their extracts from soaking in water mainly contain plant-derived active compounds, and currently there is no evidence indicating interactions between these compounds and vaccine components. If there are no post-vaccination symptoms such as fever, fatigue, or rash, and if the individual has previously consumed Dendrobium-Salvia infusion without experiencing allergies or gastrointestinal discomfort, moderate consumption is acceptable and can exert its normal regulatory effects without the need for deliberate avoidance.

Generally, if there are no adverse reactions after vaccination and no history of related allergies, it is acceptable to moderately consume浸泡water made from Dendrobium (Shihu) and Salvia (Danshen). However, if discomfort or allergic reactions occur after vaccination, consumption is not recommended. If in doubt, it is advisable to consult a healthcare professional beforehand. Detailed analysis is as follows:

Dendrobium and Salvia are common substances considered both food and medicine. When steeped in water, their components are primarily plant-derived active compounds. Currently, there is no evidence indicating that these components interact with vaccine ingredients or interfere with the immune system's response to vaccines. If there are no post-vaccination symptoms such as fever, fatigue, or rashes, and if previous consumption of Dendrobium-Salvia infusion did not cause allergies or gastrointestinal discomfort, moderate intake can be continued for its general health-regulating benefits without special avoidance.

If adverse effects such as fever, dizziness, or nausea occur after vaccination, or if one has known allergies to either Dendrobium or Salvia, or suffers from weak gastrointestinal function (e.g., prone to diarrhea), consuming this infusion may worsen physical discomfort. Additionally, overlapping symptoms could make it difficult to distinguish between vaccine-related side effects and reactions caused by the drink. Moreover, since Salvia has mild blood-activating properties, it is also advisable to avoid consumption temporarily if there is slight redness or swelling at the injection site, to prevent potential local irritation.

Before drinking, ensure you have no history of allergies to these herbs. First-time users should start with a small amount. After vaccination, closely monitor your physical condition; if any new discomfort arises after consumption, discontinue immediately and promptly inform your doctor about both your vaccination and the use of this herbal infusion.
