(1) Henna: 
The Prophet also recommended using henna for more than hair colouring:
“Whenever somebody came to Prophet Muhammad (Pbuh) with complaints of headache, he directed him to undergo cupping and whosoever complained of pain in legs, was advised to apply Henna.” (Bukhari, Abu Dawood)
has a sudden headache, he would dye his hair with Henna.
Females
generally stay up till the depths of the night, applying the greenish
Henna paste to each other's hands, waiting for it to dry, and washing
it off to reveal beautiful orange-brown designs; ready to celebrate the
blessed day of Eid.
The actual Henna plant - the lawsonia inermis
grows in clusters of small, intensely fragrant flowers. Sometimes the
flowers are pink or red, but usually they are white. The Perfume made
from henna flowers is very sweet and strong.
In a well known hadith, it is recorded that Muhammad
said, "the lord of sweet-smelling blossoms in this world and the next is Henna blossom"
[Burayda, as-Suyuti's 'Tibb an-Nabi']
Anas (RadiAllahu anhu) also relates that that Prophet loved sweet-smelling blossoms, especially that of Henna.
[Bayhaqi]
There
are many names given around the world to this plant - Henna, Hinna,
Mehandi, Mendee, Al-Khanna, Al- henna, khidab, Jamaica Mignonette,
Egyptian Privet, Smooth Lawsonia, and others. However, whatever name it
is given, it most surely deserves to be called "The Prince of Dyes", as
given by the Prophet Muhammad
