Overall, Chinese gallnut extract is safe when used properly and appropriately. However, its potent pharmacological activity also implies clear contraindications and potential risks.

The following are key aspects of its safety analysis:

1.. Major Safety Risks and Side Effects

• Gastrointestinal Irritation and Liver Damage Risk (Major Risk)
• Impairment of Nutrient Absorption
• Constipation

2. Contraindications and Precautions

• Pregnant and Breastfeeding Women: Due to the lack of sufficient safety data, oral administration should be avoided as a precaution.
• Children: Due to incomplete liver development, use of this extract requires strict medical guidance and dosage control.
• Patients with Hepatic Insufficiency: Use with caution or contraindications is contraindicated.

Galla Chinensis Extract is included in the Catalogue of Used Cosmetic Raw Materials (2021 Edition), and the INCI name is: GALLA RHOIS GALLNUT EXTRACT. This raw material needs to be used in accordance with the requirements of the "Technical Specifications for Safety of Cosmetics". Mouthwash containing gallnut ingredients not only has the properties of anti-infection, analgesia, antibacterial and anti-resistant bacteria, but also the safety of traditional Chinese medicine preparations is relatively high, so it has good prospects in clinical application. In the process of fixed orthodontics for adolescents, the combined use of fluoride foam and compound gallnut mouthwash is a combination of traditional Chinese medicine's dialectical treatment method, which has fewer side effects, stronger targeting and higher safety.

1. Powerful Astringency and Antidiarrheal Effect

The most notable benefit of gallnut extract lies in its powerful astringency. This is primarily due to its core component, tannic acid, which can contain over 70% of the active ingredient. When taken orally, tannic acid binds to the proteins of the gastrointestinal mucosa, forming a dense protective layer that effectively reduces inflammatory exudates and intestinal fluid secretions. It also inhibits excessive peristalsis of intestinal smooth muscle, significantly slowing the passage of intestinal contents and producing a highly effective antidiarrheal effect. Therefore, it is often used clinically to treat acute and chronic diarrhea and colitis caused by non-infectious factors.

2. Broad-Spectrum Antibacterial and Antiviral Effects

Gallnut extract possesses natural antibacterial and antiviral properties. Tannic acid can coagulate and denature proteins in microorganisms, disrupting their structure and function. Modern pharmacological research has confirmed that it has significant inhibitory effects against many common pathogens, such as Staphylococcus aureus, Streptococcus, and Shigella dysenteriae, and also has inhibitory effects against certain influenza viruses. This property makes it an ideal natural ingredient for treating oral ulcers, gingivitis, pharyngitis, and other oral and throat infections, as well as bacterial infections on the skin and burn wound care.

3. Effective Hemostasis and Healing Promotion

Thanks to its protein-coagulating properties, gallnut extract is a highly effective topical hemostatic. When applied to minor wounds, abrasions, or bleeding from the gums or nasal mucosa, it rapidly coagulates local blood proteins and constricts capillaries, effectively stopping bleeding. Furthermore, the protective film formed on the wound surface not only prevents secondary infection but also reduces interstitial fluid exudation, creating a clean, dry environment for granulation tissue growth, thereby effectively accelerating the healing process of ulcers and wounds.

4. Strengthening Teeth and Preventing Caries

In the field of oral care, gallnut extract plays a vital role. It effectively inhibits the activity and growth of caries-causing bacteria in dental plaque and interferes with bacterial attachment to tooth surfaces. Its astringent properties also help strengthen tooth enamel's resistance to acid corrosion. Based on these mechanisms, it is widely added to toothpaste and mouthwash for daily use to prevent tooth decay, alleviate gingivitis and periodontitis, and maintain healthy teeth and gums.

5. Antioxidant and Skin Protection

In addition to its traditional medicinal properties, gallnut extract also exhibits excellent antioxidant properties. The polyphenols it contains are powerful natural antioxidants that effectively scavenge free radicals in the body and mitigate cellular damage caused by oxidative stress. In skincare products, it is used as an astringent and preservative, helping to tighten pores, control oil secretion, and protect skin cells from oxidative damage caused by environmental pollution, thereby helping to slow down skin aging.

1. Pharmaceutical Manufacturing

In the pharmaceutical industry, gallnut extract is an indispensable natural ingredient. Its core benefits—strong astringency and antibacterial properties—make it a key ingredient in non-infectious diarrhea treatments (such as antidiarrheal tablets and oral solutions). It is also widely formulated into gargles, lozenges, and mouth sprays for the treatment of recurrent oral ulcers, gingivitis, and sore throats. In gynecology, it is also used in lotions to treat inflammation through its antibacterial and astringent properties.

2. Daily Chemicals and Personal Care

This industry is one of the most widely used areas for gallnut extract. In oral care, it is a core ingredient in many traditional Chinese medicine toothpastes and mouthwashes, designed to strengthen teeth, prevent caries, and relieve gum bleeding. In skincare, its astringent properties are used in cleansers and serums that tighten pores and control oil. Its antioxidant properties help skincare products fight free radicals and slow the aging process. It is also found in some shampoos to improve scalp health.

3. Food Industry

In the food industry, gallnut extract primarily serves as a "natural defender." As a highly effective natural preservative, it inhibits microbial growth and extends the shelf life of food. It is also an excellent clarifier, particularly in beer and juice brewing, effectively removing protein impurities, improving the clarity and stability of beverages and ensuring the purity of the product flavor.

4. Textile and Leather Industries

In these two traditional industries, gallnut extract demonstrates its unique value. In the textile industry, it is used as a natural mordant, helping dyes adhere more firmly to fibers and enhancing the colorfastness of fabrics. In the leather industry, its tannic acid binds to proteins in hides and skins, making them soft, durable, and resistant to spoilage. It is a key processing material for producing high-quality leather.
