10 Possible Side Effects Of Camellia Sinensis (Tea)
Camellia sinensis has some side effects when used improperly, such as caffeine sensitivity, digestive issues, and anxiety.
Excessive consumption can cause these problems to worsen, leading to sleep disturbances, heart palpitations, and decreased focus. Moreover, interactions with certain medications, like blood thinners, can increase the risk of bleeding and bruising.
In severe cases, this may lead to more serious health complications, such as cardiovascular disease and kidney stones.
This article explains in details the 10 most common side effects of Camellia sinensis if used imporperly.
1. Develops stomach ulcers
Camellia sinensis causes allergic reactions in some individuals.
This is often attributed to the presence of specific proteins and polyphenols in the plant, which can stimulate an immune response leading to symptoms such as hives, itching, and difficulty breathing.
Additionally, cross-reactivity with other plants or environmental allergens may contribute to the development of allergies to Camellia sinensis.
2. Develops stomach ulcers
Camellia sinensis triggers insomnia due to its high levels of caffeine, which can interfere with an individual's ability to fall asleep and stay asleep.
The caffeine in tea can stimulate the central nervous system, leading to increased alertness and energy, making it difficult for some people to wind down and relax before bedtime.
As a result, users may experience difficulty sleeping or suffer from poor quality sleep due to the stimulating effects of Camellia sinensis.
3. Develops stomach ulcers
Camellia sinensis increases heart rate due to its caffeine content.
Caffeine is a stimulant that affects the nervous system, causing an increase in heart rate and blood pressure. As Camellia sinensis contains varying amounts of caffeine depending on factors such as brewing time and method, consuming large quantities or drinking multiple cups can lead to this side effect.
The stimulating effects of caffeine can also enhance alertness and energy, but may be undesirable for individuals with pre-existing cardiovascular conditions.
4. Develops stomach ulcers
Camellia sinensis lowers blood pressure by blocking alpha-adrenergic receptors and stimulating vasodilation.
This results in a decrease in peripheral vascular resistance, leading to a drop in blood pressure.
Additionally, the flavonoids present in tea, such as epigallocatechin gallate, have been shown to inhibit angiotensin-converting enzyme, further contributing to the hypotensive effect.
5. Develops stomach ulcers
Camellia sinensis produces gastrointestinal issues due to its high content of catechins, particularly epigallocatechin gallate (EGCG).
EGCG can increase gut motility and alter the balance of gut flora, leading to symptoms such as diarrhea, abdominal pain, and nausea.
Additionally, Camellia sinensis contains caffeine, which can further exacerbate gastrointestinal issues by increasing stomach acid production and altering bowel habits.
6. Develops stomach ulcers
Camellia sinensis induces anxiety attacks due to its high caffeine content.
The stimulating effects of caffeine can lead to an increased heart rate and blood pressure, causing feelings of jitteriness and unease. Additionally, the amino acid L-theanine, although commonly found in tea, can have a paradoxical effect on some individuals, exacerbating anxiety rather than promoting relaxation.
This anomaly is thought to be linked to individual differences in brain chemistry and neurotransmitter functioning.
7. Develops stomach ulcers
Camellia sinensis causes respiratory problems due to its high caffeine content.
The stimulant properties of caffeine can exacerbate conditions such as bronchitis, asthma, and chronic obstructive pulmonary disease (COPD), leading to coughing, wheezing, and shortness of breath.
Additionally, the histamine present in tea can further aggravate respiratory issues by causing increased mucus production and constriction of airways.
8. Develops stomach ulcers
Camellia sinensis provokes digestive disorders due to its high caffeine content.
The stimulant property of caffeine can irritate the stomach lining, leading to symptoms such as bloating, gas, and stomach upset.
Additionally, Camellia sinensis may contain polyphenols, which can interfere with digestion and absorption of nutrients, potentially causing abdominal discomfort and diarrhea in some individuals.
9. Develops stomach ulcers
Camellia sinensis enhances sensitivity to light due to its high content of caffeine and flavonoids.
These compounds can increase the production of reactive oxygen species (ROS) in the body, which can lead to an overactivation of the skin's melanocytes, causing increased pigmentation and enhanced sensitivity to UV radiation.
As a result, individuals using Camellia sinensis may experience discomfort when exposed to bright lights or direct sunlight, leading to a heightened awareness of their surroundings.
10. Develops stomach ulcers
Camellia sinensis leads to headaches due to its caffeine content.
The high levels of caffeine in tea can cause an increase in blood pressure and heart rate, leading to a pounding sensation in the head.
Additionally, caffeine's stimulant properties can irritate the nervous system, causing tension and discomfort that manifests as a headache.
