Di Gu Pi, also known as Chinese Wolfberry Root-bark or Lycii Cortex, is a traditional herb widely used in Chinese medicine. Derived from the dried root bark of the Lycium chinense or Lycium barbarum plants (commonly known as goji berry plants), it has been valued for centuries for its medicinal properties.
In this article, we will explore what Di Gu Pi is, its potential health benefits, and any associated risks.
What is Di Gu Pi?
Di Gu Pi (地骨皮), often translated as “Chinese Wolfberry Root-bark,” refers specifically to the root bark of the goji plant. While goji berries are more commonly recognized for their superfood status, the root bark has its own significant role in traditional Chinese medicine (TCM)1.
It has been historically used to treat various ailments, particularly those associated with lung heat, fever, and diabetes. The herb is classified as cooling in nature, meaning it can help reduce heat and inflammation in the body2.
Key chemical compounds in Di Gu Pi include betaine, lyciumamide, atropine, and a range of organic acids and sterols. These compounds contribute to its medicinal effects3.
Benefits of Di Gu Pi
Di Gu Pi has been traditionally used for a variety of health issues. Some of its most notable benefits include:
1. Reducing Fever and Heat
One of Di Gu Pi’s primary functions is cooling the body, particularly in cases of yin deficiency. This herb is often prescribed to those suffering from low-grade fevers, night sweats, and conditions associated with “bone steaming” fever (a TCM term for internal heat, often experienced after illness)4.
For example, a person recovering from a prolonged illness might experience persistent low fever. In this case, This herb can help cool the internal heat and restore balance.
2. Clearing Lung Heat and Relieving Cough
In TCM, this herb is known for its ability to cool the lungs and alleviate symptoms of lung heat. This is particularly helpful for treating dry coughs or coughing up blood, both signs of excessive heat trapped in the lungs5.
It’s often paired with other herbs like mulberry bark (Sang Bai Pi) and licorice root (Gan Cao) to create formulas such as Xie Bai San, which help clear lung heat and soothe respiratory discomfort.
3. Cooling Blood and Stopping Bleeding
This herb is also effective for treating various types of heat-induced bleeding, such as nosebleeds, coughing up blood, or even blood in the urine. Its cooling and blood-purifying properties help stop bleeding by reducing the excess heat in the blood6.
4. Managing Diabetes and High Blood Pressure
Modern research has found that Di Gu Pi may help manage blood sugar and blood pressure7. The herb has a hypoglycemic effect, making it potentially beneficial for those with diabetes. Additionally, studies show that it can help lower blood pressure and improve overall cardiovascular health by reducing inflammation and improving circulation8.
5. Reducing Inflammation
Some research indicates that Di Gu Pi has anti-inflammatory effects, which could make it useful in treating conditions like arthritis or skin inflammations. Its ability to cool the blood and reduce internal heat makes it helpful for calming inflammation throughout the body9.
Risks and Side Effects
While Di Gu Pi has many potential benefits, it’s important to be aware of its possible side effects1011:
- Nausea and Vomiting: Some individuals may experience gastrointestinal discomfort, such as nausea, vomiting, or diarrhea, particularly when consuming it in large doses.
- Dizziness or Heart Palpitations: Certain compounds in Di Gu Pi, like atropine, may cause symptoms like dizziness or irregular heartbeat in sensitive individuals.
- Skin Rash: Allergic reactions, although rare, could manifest as rashes or skin irritation.
It’s also important to note that individuals with cold-related illnesses (such as the common cold or flu) or those with spleen deficiency should avoid it, as it can exacerbate these conditions.
Preparation and Usage
In traditional Chinese medicine, Di Gu Pi is typically prepared by boiling the dried root bark in water to create a decoction. The recommended dosage is usually between 6 to 15 grams per day, but it’s essential to consult with a qualified TCM practitioner for personalized advice12.
Note: This herb is often combined with other herbs to enhance its effects. For instance, it is commonly used with zhi mu (Anemarrhena asphodeloides) and tian hua fen (Trichosanthes kirilowii) to create more potent remedies13.
Conclusion
Di Gu Pi is a versatile herb with a long history in traditional Chinese medicine. From reducing fever to managing lung conditions and lowering blood sugar, it offers various benefits. However, like any medicinal herb, it should be used cautiously and under the guidance of a healthcare professional, especially if you’re dealing with preexisting conditions or are sensitive to its side effects.
If you’re curious about adding Di Gu Pi or any other traditional herb to your wellness routine, it’s best to consult with a TCM expert who can tailor treatments to your specific needs.
