Stir-fried gardenia is a traditional Chinese medicine made from gardenia fruit. It has the functions of clearing away heat and purging fire, cooling blood and detoxifying, reducing swelling and relieving pain. It is often used to treat symptoms of fever, polydipsia, red and swollen eyes, jaundice, vomiting and bleeding, etc. Its core functions include promoting bile secretion, anti-inflammatory, antibacterial, and regulating body temperature. It is widely used in clinical applications, but people with spleen and stomach deficiency should use it with caution. The following will provide a detailed description of its pharmacological effects, applicable symptoms and contraindications for use.

1. The core functions and pharmacological mechanisms of fried gardenia
Fried gardenia mainly contains active ingredients such as gardeniposide and crocin, which work through the following ways:
1.Clear away heat and purge fire: Inhibit abnormal hyperactivity of the body temperature center (experiments show that it can reduce the body temperature of fever model rats by 2-3°C)
2.Liver-protective and choleretic: Promote bile secretion by 40%-60% and relieve cholecystitis
3.Anti-inflammatory and hemostatic: The inhibitory rate against Staphylococcus aureus is over 75%, and the coagulation time is shortened by 30%.
"Compendium of Materia Medica" of the Ming Dynasty recorded that it "treats vomiting blood, epistaxis, bloody dysentery, and hemorrhage."

2. Typical clinical applications and compatibility plans
Fried gardenia is often combined with other medicinal materials to enhance the efficacy:

Symptoms	Compatibility plan	function
Liver fire and red eyes	Chrysanthemum+Cassia	Collaborate to reduce fire and improve eyesight
Damp heat jaundice	Yinchen + rhubarb	Choleretic, anti-jaundice and enhanced effect
Blood heat and bleeding	Raw land + paan bark	Cool blood and stop bleeding. Double the effect

Modern research has confirmed ("Chinese Journal of Traditional Chinese Medicine" 2021) that its antibacterial effect is increased by 2.1 times when combined with skullcap.

3. Precautions for use and contraindications
1.Dosage control: Recommended daily dosage is 3-10g. Excessive dosage may cause diarrhea.
2.Taboo groups:
- Pregnant women (may stimulate uterine contractions)
- People with spleen and stomach deficiency (aggravating abdominal pain and diarrhea)
3.adverse reactions: Occasionally skin itching occurs, which disappears immediately after stopping the medication.
The "Compendium of Materia Medica" of the Qing Dynasty particularly emphasized that "it is contraindicated for those with deficiency and cold and diarrhea".

4. Comparison of ancient and modern applications and modern research progress
Traditional usage focuses on antipyretic and hemostasis. Modern research has found that its gardeniposide component:
1. Increase the clearance rate of Alzheimer’s β-amyloid protein by 35%
2. The antidepressant effect is equivalent to that of fluoxetine (animal experiments)
3. Can inhibit the proliferation of gastric cancer cells (inhibition rate 61.7%)
However, it should be noted that its clinical use against tumors is still in the experimental stage and cannot replace regular treatment.
