It is in April when many states in India celebrate different festivals to welcome their respective new year.
Rongali Bihu or Bohag Bihu is celebrated in mid-April to mark the start of a new year.
It is a two-day festival during which, the first day is dedicated to the domestic cows and called the "Goru Bihu" and the second day is called "Manhu Bihu" which is the people's celebration day.
The Assamese people intensively use natural products to clean and cleanse themselves on the day of the manhu bihu.
A mixture of "mah" and "haldi" is made and applied all over the body before taking bath.
The period of Bohag Bihu brings happiness and good health to the lives of all people.Mah is a kind of lentil that is native to Assam. Mah is extremely good for hair and keeps hair problems like lice, dandruff and alopecia at a bay. It is also used as an alternative to shampoo to cleanse the hair.
Other than its external usage, it is also consumed in the form of liquid lentil, which is commonly known as "mati-mahor dail" and even consumed with some kind of vegetable curry.
Haldi or turmeric is also an important part of Bihu celebration. The raw haldhi is first peeled, then cut into small pieces and then a paste is made out of it.
Haldi is known for its anti-bacterial effects and is extremely beneficial for the skin. Haldi is also an extremely good pain reliever.
In Assam, it is a tradition to apply the paste of mah and haldi on the day of the Bihu and people have been constantly following this tradition for ages with full dedication.
