Traditional Chinese Medicine Consultation


Hello Dr.
Yan: I would like to ask about a Chinese medicine prescription I received, which includes the following: Xiao Yao San 4g, Yan Hu Suo 1.5g, Sha Ren 1.5g, Ping Wei San 3g, Chai Hu Shu Gan Tang 3g, and Chuan Lian Zi 1g (daily dosage).
I am instructed to take it after meals for 7 days.
I am concerned about the potential effects on the liver and kidneys due to the small toxicity of Chuan Lian Zi.
Will this have any impact on my liver and kidneys? Additionally, do the other ingredients in the prescription also affect the liver and kidneys? Thank you, Dr.
Yan.

Hami Guo, 30~39 year old female. Ask Date: 2018/05/01

Dr. Yan Sumei reply Traditional Chinese Medicine


Dear Melon: Thank you for your letter.
Fructus Meliae (Chuan Lian Zi) has mild toxicity, primarily hepatotoxicity.
It is recommended for short-term use, not exceeding one month.
If you have any concerns, please ask your traditional Chinese medicine practitioner to adjust your prescription during your next visit to avoid any worries.
Other herbal medicines are commonly used and have not been reported to have toxicity, so you can take them with peace of mind.
Wishing you health and safety! Sincerely, Su-Mei Yen, Department of Traditional Chinese Medicine, Nantou Hospital.

More Info


When consulting Traditional Chinese Medicine (TCM) and considering the safety of herbal prescriptions, it is essential to understand both the individual herbs and their potential interactions with other medications or health conditions. In your case, you mentioned a prescription that includes several herbs, including Chuan Lian Zi (川楝子), which is known to have some toxic properties if used improperly.


Safety of Herbal Prescriptions
1. Understanding the Herbs:
- Chuan Lian Zi (川楝子): This herb is often used for its analgesic and anti-inflammatory properties, but it does contain compounds that can be toxic in high doses. It is crucial to adhere to the prescribed dosage and duration of use. In your case, the amount prescribed (1g per day) is generally considered safe for short-term use, especially when taken as directed.

- Xiao Yao San (逍遙散): This formula is commonly used for stress relief and to promote liver health. It is generally safe for most individuals.

- Yan Hu Suo (延胡索): Known for its pain-relieving properties, it is also considered safe when used appropriately.

- Sha Ren (砂仁): This herb is often used to aid digestion and is typically safe.

- Ping Wei San (平胃散): This formula is used to improve digestion and is generally well-tolerated.

- Chai Hu (柴胡): Often used to relieve liver Qi stagnation, it is also considered safe.

- Gan Cao (甘草): This herb is used to harmonize other herbs in a formula and is generally safe.


2. Potential Effects on Liver and Kidney:
- While Chuan Lian Zi has some potential for toxicity, when used in moderation and under the guidance of a qualified practitioner, the risk of significant harm to the liver or kidneys is low. However, it is always prudent to monitor for any adverse effects, especially if you have pre-existing liver or kidney conditions.

- The other herbs in your prescription are generally considered safe for the liver and kidneys when taken as directed. However, individual responses can vary, and it is essential to communicate any pre-existing health conditions to your TCM practitioner.

3. Interactions with Other Medications:
- If you are taking Western medications or other herbal supplements, it is vital to inform your TCM practitioner. Some herbs can interact with medications, potentially altering their effectiveness or increasing the risk of side effects. For example, certain herbs may affect liver enzymes that metabolize medications, leading to either increased toxicity or reduced efficacy.

4. Monitoring and Consultation:
- It is advisable to have regular follow-ups with your TCM practitioner to monitor your response to the herbal treatment. If you experience any unusual symptoms, such as gastrointestinal distress, fatigue, or changes in urination, you should report these to your practitioner immediately.

- If you have concerns about the specific effects of any herb on your liver or kidney health, consider discussing these with a healthcare provider who specializes in both TCM and Western medicine.

5. General Recommendations:
- Always follow the prescribed dosage and duration of herbal treatments.

- Maintain open communication with your healthcare providers about all medications and supplements you are taking.

- Consider lifestyle factors such as diet, hydration, and stress management, as these can significantly impact your overall health and the effectiveness of herbal treatments.

In conclusion, while your prescribed herbal formula appears to be safe when taken as directed, it is essential to remain vigilant and consult with your TCM practitioner regarding any concerns, especially related to liver and kidney health. Regular monitoring and open communication with your healthcare providers will help ensure the safe and effective use of herbal medicine.
