How is black tea made and how does it taste?

Black tea, one of the most popular worldwide drinks, is made from leaves of a shrub called Camellia sinensis.

Tea leaves undergo different processing methods that produce various types of tea. After harvesting, the leaves are withered, rolled, heated, and fermented. Some leaves are left in the air to oxidize. The color and flavor of leaves depend mostly on oxidation and the fermentation processes.

Tea leaves are brewed in hot water or boiled for a few minutes until the water turns dark brown, indicating that the flavor of the leaves is well incorporated in the water.

Black tea might taste bitter initially and is usually drunk with or without adding other ingredients, such as sugar, milk, or lemon for additional flavor and taste. It is recommended to avoid such additives to get all of the black tea benefits.

What are the side effects of black tea?

Drinking black tea in moderation is usually safe. However, there is no particular standard dose on how much tea should be consumed. It solely depends on the person and how their body reacts to it.

Herbal tea (such as black tea, white tea, and green tea) contains caffeine, and drinking a large quantity can cause side effects related to caffeine overdose, which include:

• Increased breathing
• Increased urine frequency
• Nausea and vomiting
• Diarrhea or constipation
• Anxiety
• Sleeping problems
• Headache
• Changes in heart rate
• High blood pressure
• Anemia (low red blood cells)
• Tinnitus (ringing in the ears)
• Tremors
• Nervousness
• Restlessness
• Seizures
• Gastritis

Black tea and its supplements may interact with other medications and supplements that you regularly take. Some medications might cause caffeine to linger in your system for a longer period than usual. Consult your doctor to see whether any medications you are taking may have this effect.

Caffeine, which is included in black tea and green tea, may potentially interfere with some blood tests. Inform your doctor about any supplements you are taking, including natural supplements, and those purchased without a prescription. Additionally, inform your doctor if you consume a lot of these beverages.
