How Henna is Colored
Currently the line of Henna offered by Mountain Rose Herbs is made exclusively with Lawsonia inermis, with other botanical ingredients included for the purpose of creating the many different shades which we have to offer.
Mountain Rose Herbs Henna is colored using one or more of the following botanical methods which are included into the Henna during manufacture.....
Henna leaf (Lawsonia inermis)
Henna Bark (Lawsonia inermis)
Indigo leaf and stalk
Calendula petals
Chamomile flowers
Hibiscus flowers
Alkanet root
The Calendula and Chamomile are used to lighten certain Henna colors, the Hibiscus and Alkanet are use to add Red highlights, and the Indigo is used to darken some of the Henna colors. The Indigo is a natural shrub in the legume family that thrives in dry and almost poor conditions. To date most of it is commercially grown in India, but the Chinese and other Southeast Asian countries are growing it with much success. There is a fabulous profile of it on Botanical.com, please see..... http://botanical.com/botanical/mgmh/i/indigo05.html
But we should point out that this published material is over 75 years old and in that time there have been several more introduced Indigo varieties that are being employed for coloring reasons. For a more recent profiles, please see....
