Can American ginseng be steeped in water for long-term consumption?
Generally speaking, American ginseng is not recommended for long-term consumption as a herbal tea. Detailed explanations are as follows:

American ginseng has a cold nature, and long-term consumption may damage the body's yang energy. Particularly for individuals with a cold constitution, prolonged use could worsen symptoms of cold sensitivity, such as chills, cold limbs, abdominal pain, and diarrhea. Even for those with a normal constitution, long-term consumption of cold-natured American ginseng may gradually impair yang energy, leading to symptoms like cold intolerance and decreased immunity.
Although American ginseng has certain nourishing (yin-enhancing) effects, long-term excessive consumption may cause excess yin in the body, leading to internal dampness and phlegm. This may manifest as coughing with excessive phlegm, bodily heaviness, fatigue, poor appetite, and other related symptoms. Over-nourishing yin may also impair the spleen and stomach's transformation and transportation functions, causing symptoms such as indigestion and abdominal distension. Traditional Chinese Medicine emphasizes the balance between yin and yang in the body. Long-term, exclusive use of American ginseng may disrupt this balance, potentially causing various physical discomforts.
To ensure safety and health, it is recommended to consult a qualified TCM practitioner before consuming American ginseng tea over a long period. Personalized guidance based on individual constitution and health status is important. Additionally, pay attention to your body's response, and if any adverse reactions occur, discontinue use immediately and seek medical advice. In daily life, maintaining a balanced diet and engaging in moderate exercise can help improve overall health.
