Here's a breakdown:
Henna Leaves: The main ingredient is the dried leaves of the henna plant, Lawsonia inermis. These leaves contain a dye called Lawsone, which is responsible for the reddish-brown color of the tattoo.
Water: Water is used to create a paste from the henna powder. It helps to extract the Lawsone and create a smooth, workable consistency.
Other Ingredients:
* Lemon juice: Helps to release more Lawsone from the henna leaves and make the color darker.
* Strong tea: Can add a slightly darker hue to the final stain.
* Essential oils: Often added for their fragrance and potential antimicrobial properties. Common choices include eucalyptus oil, tea tree oil, and clove oil.
Important Note: Black henna is not made from henna leaves. It usually contains a chemical dye called paraphenylenediamine (PPD), which can be dangerous and cause severe allergic reactions. It is crucial to use only natural henna paste for safe and authentic henna tattoos.
