This food additive called "Khar" is very popular in Assam, a North-Eastern …
How Tea is Made – Camellia Sinensis Camellia Sinensis is an evergreen plant and a member of the Theaceae family of shrubs. In the wild, it can grow up to 6 meters, 19.6' tall, but in a controlled environment, its cultivation is normally kept at around 1.2m, 4' in order to make cultivated leaves more accessible.
Figure 2 Schematic diagram of green synthesis of silver nanoparticles 2.3. AgNP Synthesis in Plants To synthesize AgNPs, plant extracts were being used and because of their availability, low toxicity, and safety, they may be preferable to bacterial and fungal synthesis [16]. AgNPs' properties are determined by the plant extract sources.
