Introduction
In general, drinking wild vine tea may cause side effects such as gastrointestinal discomfort, allergic reactions, sleep disturbances, worsening of hypoglycemia, and irritation of oral mucosa. In addition, consumption should be moderated to avoid excessive or long-term intake. Pregnant women, nursing mothers, and other special populations are advised to consult a healthcare professional before deciding whether to consume wild vine tea to ensure safety.
Generally, drinking wild vine tea may cause side effects such as gastrointestinal discomfort, allergic reactions, sleep disturbances, worsening of hypoglycemia, and irritation of oral mucosa. The specific analysis is as follows:
1. Gastrointestinal Discomfort
Wild vine tea has a relatively cooling nature and contains certain tannins. For individuals with weak spleen and stomach function, the tannins may irritate the gastric mucosa, while the cooling property can impair the yang energy of the spleen and stomach, possibly causing discomfort such as bloating, diarrhea, and nausea. Therefore, people with cold deficiency in the spleen and stomach should consume it cautiously.
2. Allergic Reactions
Wild vine tea contains active substances such as flavonoids and polyphenols, to which some individuals may be sensitive. After consumption, the immune system may produce abnormal responses, leading to symptoms like skin itching, red rashes, or urticaria. In severe cases, difficulty breathing may also occur. Thus, individuals with allergic predispositions should avoid drinking it.
3. Sleep Disturbances
Wild vine tea contains small amounts of components that stimulate the central nervous system. Drinking it before bedtime may activate the nerves, keeping the brain in an alert state, disrupting normal sleep rhythms, and potentially causing difficulties falling asleep or lighter sleep, thereby negatively affecting sleep quality.
4. Worsening of Hypoglycemia
Studies suggest that wild vine tea may assist in regulating blood glucose levels. Diabetic patients or individuals with hypoglycemia may experience enhanced insulin effects after consuming it, leading to further drops in blood sugar and symptoms such as dizziness, fatigue, and palpitations. These individuals should consult a doctor before drinking it.
5. Irritation of Oral Mucosa
Wild vine tea contains high levels of tannins and tea polyphenols, which can irritate the oral mucosa. Long-term or excessive consumption may lead to dryness and astringency in the mouth, and could also affect dental health by increasing the risk of enamel damage.
In addition, intake of wild vine tea should be controlled to avoid excessive or prolonged consumption. Special populations such as pregnant women and lactating mothers are advised to consult professionals before deciding whether to consume it, to ensure safety.
