The health benefits of losing weight have encouraged many individuals to drink green tea every day. As reported by the Tea Board of India, around 8,370,000 tonnes of tea is consumed in India, with about 10-12 percent of this amount being green tea. However, it’s important to note that like any natural remedy, some individuals might be allergic to green tea. The allergy symptoms can include losing hair excessively, a drop in biotin levels, known as vitamin B12, liver damage, and even trouble with breathing. Although green tea allergies are uncommon and can vary depending on the specific variety of green tea consumed, several cases have been documented. Different people have unique responses to new substances introduced to their bodies. Green tea is created from the leaves and buds of the camellia sinensis plant. Research indicates that both children and adults who drink green tea over time may experience liver issues, like liver swelling, due to catechins found in green tea bags when brewed. Each person’s immune system reacts uniquely, as proteins from the green tea plant can trigger health problems.

It is essential to determine whether you have an allergy or intolerance to green tea. Some signs can help individuals figure out if they are allergic or intolerant to green tea for safe consumption.

The various types of green tea available can lead to different reactions upon intake. Many people choose green tea for its weight loss advantages, but weight loss is a personal experience that varies between individuals. There isn’t a guaranteed way to lose weight simply by drinking green tea. Research shows that using green tea without proper guidance can lead to serious symptoms, so it’s vital to recognize these if you are currently drinking green tea or considering it for health benefits:

Individuals can experience both outside and inside symptoms based on factors such as the length of time they drink green tea, the form they consume, and the reason for their intake. These symptoms may include:

Skin issues: hives, itching, swelling.
Breathing difficulties: nasal blockages, trouble with breathing. If you struggle to breathe, seek urgent medical help.
Digestive distress: feelings of nausea, cramps, and diarrhea.
Extreme cases: anaphylaxis (rare, emergency situation).

There have been documented instances of severe green tea allergies in both children and adults, but further research is necessary given how commonly it is used in India. Studies have found that certain proteins in green tea can cause reactions leading to serious health concerns. If these proteins are not fully broken down by the body, they can trigger allergic responses. It is crucial for individuals to be aware of their own health needs and to consult with a healthcare professional before consuming green tea.

Proteins such as EGCG and 70-kDa protein are found in green tea, and they may cause allergic responses because they are recognized as allergens.
Individuals who are sensitive to tannins or have issues digesting caffeine should be cautious when taking store-bought green tea.
Considering the present condition of the environment along with increasing air and water pollution, some people may have a genetic tendency to react to green tea.

Research also shows that drinking green tea together with other plant-based beverages can lead to various reactions in the body.
