Black, white, and green teas are natural sources of caffeine and may increase your risk of symptoms. There is an exception. Decaffeinated herbal teas may help you manage symptoms of GERD and acid reflux.
Generally speaking, coffee takes the (lower-scoring and acidic) biscuit, but it depends on what tea you're drinking. Coffee averages between 4.85 and 5.13 in pH. In contrast, green tea sits between 7 and 10.

It is very relaxing.

Less Degradation: Lower temperatures prevent oxidation of beneficial compounds.
Green tea is more delicate than black tea, and should never be brewed with boiling water: the heat extracts tannins, giving your tea a bitter, astringent flavour. Use water off the boil (around 80°C) – leave the kettle after boiling for five minutes, then pour and infuse for 2–3 minutes.
The healthiest green tea is often considered Matcha, as you consume the whole powdered leaf, maximizing antioxidants like EGCG, but high-quality, shaded teas like Gyokuro and everyday Sencha are also excellent, packed with nutrients. For daily use, Sencha offers great benefits, while Genmaicha provides a nutty, robust flavor, and choosing organic, loose-leaf varieties ensures a cleaner, more potent brew.
Antioxidants help decrease inflammation in the body, which can be helpful for your kidneys. Green tea has also been shown to decrease the risk of kidney stones. In particular, green tea contains the catechin epigallocatechin-3-gallate (EGCG), which may be helpful for people with kidney disease.
Meta-analysis showed that green tea consumption caused a significant reduction in systolic blood pressure and total and LDL cholesterol. The effects on diastolic blood pressure, HDL cholesterol, and triglycerides were not significant.
