Introduction
When cough presents as dry cough without phlegm, dryness and itching in the throat, heat in the palms and soles, or other symptoms of lung dryness due to yin deficiency, Ophiopogon (McDoor) may be used in small amounts to moisten the lungs and relieve cough. However, the dosage must be strictly controlled and combined with neutralizing herbs such as枇杷叶 (loquat leaf) to avoid excessive coldness that may harm the fetus. If cough is accompanied by clear, white phlegm, cold intolerance, or diarrhea and cold stomach caused by spleen and stomach deficiency, the cold nature of Ophiopogon may worsen the body's cold symptoms and affect fetal stability.
Generally, if a pregnant woman has cough due to yin deficiency and internal heat without obvious signs of cold syndrome, Ophiopogon (McDoor) can be used cautiously. However, it is not recommended for those with cough caused by wind-cold or spleen-stomach cold deficiency. If in doubt, consult a doctor in advance. Detailed analysis is as follows:
When cough presents as dry cough without phlegm, dry and itchy throat, warm palms and soles, and other symptoms of lung dryness due to yin deficiency, a small amount of Ophiopogon can be used to moisten the lungs and relieve cough. The dosage must be strictly controlled and combined with neutralizing herbs such as loquat leaf to avoid excessive coldness that could harm the fetus.
If cough is accompanied by clear and thin white phlegm, cold intolerance, cold abdomen, or diarrhea caused by spleen-stomach weakness and gastrointestinal dysfunction, Ophiopogon's cold nature may worsen internal cold symptoms and affect fetal stability. Warm-natured herbs such as Amomi Fructus Rotundus and Tangerine Peel should be primarily considered for regulation.
Pregnant women should maintain a positive and optimistic mindset, follow a balanced diet, engage in moderate exercise, attend regular prenatal checkups, and follow professional medical advice to ensure the health of both mother and baby.
