Traditionally in South India betel leaves, areca nut, coconut, turmeric and flowers are given to females on most auspicious occasion and is known as tambulam During weddings this given to both males and females in decorative carry bags when the guests leave the marriage hall. Chewing the combination of betel leaves, areca nut and lime (Chunna) is supposed to help digestion after heavy meals and you can see in most South Indian weddings a plate with these ingredients are place outside the dining hall for the guest. This combination is generally chewed and swallowed.
In North India it is also consumed and is known as Paan and various combinations are eaten. Saada paan that just has betel leaves, areca nut and lime, Meetha paan with additional ingredients such as sweetener and so forth, or with tobacco. Normally the paan with tobacco is chewed and then spat out… you can see splotches of red markings on roads, walls, railway platforms etc in most Indian cities on account of these. Each of these paan shops try to bring out unique paans with assorted ingredients so as to catch fancy of the consumer and one such paan is the burning Paan. I came across this video about this paan and am sharing this with you all. It is all in the taste of the consumer and I find it quite surprising that such things happen in spite of the health hazards. Enjoy the Burning Paan :)
