Mahonia Fruit (Gonglaozi)
Alright, let's dive into Mahonia Fruit, known as Gonglaozi in Traditional Chinese Medicine (TCM). This isn't just any berry; it’s valued for its unique properties and how it interacts with your body.
Taste and Nature: It's got a bitter taste and a cool nature. Think of it as having a refreshing, slightly cooling effect on your system.
Meridian Tropism: Gonglaozi primarily affects the Spleen, Kidney, and Bladder Meridians. In TCM, these meridians are like energetic pathways connected to specific organ systems and their functions, influencing everything from digestion to fluid balance and vitality.
Medicinal Part: We're talking about the fruit from specific plants in the Berberidaceae family, specifically the Broadleaf Mahonia (Mahonia bealei), Slenderleaf Mahonia (Mahonia fortunei), or South China Mahonia (Mahonia fordii).
Morphological Characteristics: These are oval-shaped berries, usually about 5-8mm across. They have a distinctive dark blue surface, often coated with a powdery, waxy white layer, and they might appear a bit wrinkled. At the base, you'll see a small, round scar where the stem was. If you peel back the skin, you'll find two brownish seeds inside. They don't have a strong scent but definitely carry that bitter taste we mentioned.
How to Use Mahonia Fruit (Gonglaozi) and Dosage
Internal Use: The most common way to take Gonglaozi is by preparing it as a decoction (that's like a strong herbal tea). The typical dosage ranges from 6 to 9 grams, or you can steep it as a regular herbal tea. As with any herbal remedy, always consult a qualified TCM practitioner or healthcare provider before use to ensure it's appropriate for your specific condition and to determine the correct dosage. They can guide you safely and effectively.
Processing Method: To prepare Gonglaozi, the fruit clusters are typically harvested in June. They are then sun-dried, and the fruits are gently rubbed off the stems. After removing any impurities, they are sun-dried again until they are completely free of moisture and ready for use.
Functions and Main Indications of Mahonia Fruit (Gonglaozi)
Functions: Gonglaozi is primarily known for three key actions in TCM:
- Clears Deficiency Heat: This means it helps cool down internal heat that arises not from an acute infection, but rather from an underlying imbalance or depletion in the body.
- Tonifies the Kidneys: It helps strengthen and support the vital functions associated with the Kidneys in TCM, which includes aspects of energy, reproduction, bone health, and aging.
- Dries Dampness: It aids in resolving excess dampness in the body, which can contribute to various uncomfortable symptoms.
Main Indications: With those functions in mind, Gonglaozi is traditionally used to address a range of issues, including:
- Bone-steaming fever and tidal hot flashes: This refers to a persistent, low-grade fever that feels deep in the bones, often worse in the afternoon or evening, accompanied by periodic waves of intense heat.
- Sore and weak lower back and knees: Think chronic aches or a general feeling of lack of strength in these areas.
- Dizziness and tinnitus: When you're dealing with lightheadedness or a persistent ringing or buzzing in your ears.
- Damp-heat diarrhea: Diarrhea accompanied by a feeling of heat and heaviness, often with urgent stools.
- Vaginal discharge: Addressing abnormal or excessive vaginal discharge.
- Turbid urination: Dealing with cloudy or unclear urine, sometimes with discomfort.

- From Yin Pian Xin Can (New Insights into Decoction Pieces): "It has an astringent effect on the lower body functions, treating chronic uterine bleeding, persistent vaginal discharge, turbid urination, and diarrhea."
- From Xiandai Shiyong Zhongyao (Modern Practical Chinese Materia Medica): "Used for tidal fever and bone-steaming in tuberculosis, soreness and weakness of the lower back and knees, dizziness, tinnitus, and similar symptoms."
