What are the hazards of wooden fish stone cups

Wooden fish stone cups are usually harmless to the human body, but long-term improper use may pose potential risks. There are mainly hidden dangers such as material precipitation, improper cleaning, sudden temperature changes, counterfeit and shoddy products, and discomfort for special populations.

1. Material precipitation

Poor quality wooden fish stones may contain trace amounts of heavy metals or radioactive substances, and long-term storage of acidic beverages may lead to the slow precipitation of harmful ingredients. It is recommended to choose products that have passed national testing and certification, and avoid storing acidic liquids such as lemonade and carbonated drinks for more than 4 hours.

2. Improper cleaning

The porous structure of the wooden fish stone is prone to bacterial growth. If not cleaned in a timely manner or residual chemical detergents are used, it may cause gastrointestinal discomfort. Use a soft cloth dipped in baking soda and warm water to scrub daily. After use, dry thoroughly to avoid mold growth in damp environments.

3. Sudden temperature changes

Sudden cooling and heating may cause the cup to crack, and inferior dyes may release harmful substances at high temperatures. When brewing hot water, it is recommended to warm the cup first to avoid pouring boiling water directly after taking it out of the refrigerator. The maximum temperature tolerance is recommended not to exceed 80 degrees Celsius.

4. Counterfeit and shoddy

There is a phenomenon in the market where dyed quartzite imitates wooden fish stone, which may contain industrial dyes. The authentic wooden fish stone has a crisp and melodious knocking sound, and natural layered textures can be seen on the cross-section. When purchasing, a mineral composition testing report should be requested.

5. Discomfort for special populations

Long term use may worsen body cold symptoms for individuals with weak constitution. Pregnant women and children are advised to use glassware instead. Traditional Chinese medicine believes that wooden fish and stones have a cool nature. In winter or for people with yang deficiency constitution, ginger water can be used to regularly warm up the cup body.

It is recommended to change the type of beverage daily when using wooden fish stone cups to avoid long-term soaking of a single liquid. Before initial use, it is necessary to boil glutinous rice water for disinfection, and soak it in diluted salt water for maintenance every three months. When stored, it should be placed in a well ventilated area. If there is obvious discoloration or odor, it should be stopped immediately. Paired with bamboo coasters, it can reduce collision damage and regularly observe whether there are any minor cracks in the cup body. If you experience symptoms such as dizziness and nausea, seek medical attention promptly and bring a water bottle for testing.
