Drinking Chinese herbs does not directly cause smelly farts, but some herbs may cause digestive discomforts, such as causing stomach discomfort or flatulence, etc. These discomforts may lead to the occurrence of smelly farts. If discomfort occurs during preparation for pregnancy, it is advisable to consult a doctor or Chinese medicine practitioner for proper treatment advice. In addition, Chinese herbal medicines should be used under the guidance of a doctor or Chinese medicine practitioner and should not be abused or used arbitrarily. Drinking Chinese medicines in preparation for pregnancy triggers bad odor? Chinese herbal medicines may trigger some undesirable odors during preparation for pregnancy, which may be due to the ingredients and specific smell of the herbs. Some Chinese medicines may contain volatile components such as sulfides, ketones and alcohols, which are metabolized in the body and excreted through breath, sweat and urine, resulting in the body emitting a special odor. In addition, some odors are also produced during the decoction process of herbal medicines, especially some herbs with pungent or bitter taste. If you are concerned that the odors triggered by Chinese herbs may have an impact on your preparation for pregnancy, it is advisable to consult your doctor or Chinese medicine practitioner to understand the specific formula and usage of the herbs and make adjustments according to your personal situation. In addition, maintaining good personal hygiene and dietary habits can also help reduce the production of undesirable odors. .
