Mineral water is water containing minerals or other dissolved substances that alter its taste or give it therapeutic value. Salts, sulfur compounds, and gases are among the substances that can be dissolved in the water. Mineral water can often be effervescent. Mineral water can be prepared or can occur naturally.

In many places, mineral water is often colloquially used to mean carbonated water (which is usually carbonated mineral water, as opposed to tap water).

Traditionally mineral waters would be used or consumed at their source, often referred to as taking the waters or taking the cure, and such sites were referred to as spas, baths or wells. Spa would be used when the water was consumed and bathed in, bath when the water was not generally consumed, and well when the water was not generally bathed in. Often an active tourist centre would grow up around a mineral water site (even in ancient times; see Bath). Such tourist development resulted in spa towns and hydropathic hotels (often shortened to Hydros).

In modern times, it is far more common for mineral waters to be bottled at source for distributed consumption. Travelling to the mineral water site for direct access to the water is now uncommon, and in many cases not possible (because of exclusive commercial ownership rights). There are over 3000 brands of mineral water commercially available worldwide.^[1]

The U.S. FDA classifies mineral water as water containing at least 250 parts per million total dissolved solids (TDS), and is also water coming from a source tapped at one or more bore holes or spring, originating from a geologically and physically protected underground water source. No minerals may be added to this water.

Green tea (simplified Chinese: 绿茶; traditional Chinese: 綠茶; pinyin: lǜchá; Japanese: 緑茶; ryokucha) is a “true” tea, meaning it is made solely with the leaves of Camellia sinensis, that has undergone minimal oxidation during processing.

Green tea originates from China and has become associated with many cultures in Asia from Japan to the Middle East. Recently, it has become more widespread in the West, where black tea is traditionally consumed. Many varieties of green tea have been created in countries where it is grown that can differ substantially due to variable growing conditions, processing and harvesting time. Over the last few decades green tea has begun to be subjected to many scientific and medical studies to determine the extent of its long-purported health benefits, with some evidence suggesting regular green tea drinkers may have lower chances of heart disease and developing certain types of cancer^[1].
