]. The dye is also very important in the cottage industry in Sierra Leone where ‘gara cloth’ is made. ‘Gara’ is the Madinka word for the traditional indigo dye found in many types of textiles of Sierra Leone. The source of this dye is the ‘gara’ leaf obtained from Philenoptera cyanescens. At present the word ‘gara’ is used both for the dyeing process (using both synthetic and natural dyes) and for the dyed products[

]. It is believed that in the middle of the 19th century Susu and Madinka traders from Guinea, who came to settle in Kabala in the northern province of Sierra Leone, encouraged the native Temne women to develop gara dyeing. Traditionally woven cloth known as ‘country cloth’ dyed with gara was used by chiefs for ceremonial dresses, bridal dowry, burial clothes, court fines and gifts to important visitors. At present gara is worn by a much wider circle of people for aesthetic and cultural reasons. It is used for daily and ceremonial uniforms in some schools and offices. In the hotel industry gara is used widely as napkins, tablecloths, bedspreads, curtains and as backdrop for conference halls and lounges[

The leaves and young shoots are bruised to a pulp and made up into balls about 10 - 12 cm in diameter, called ‘arô’ in Yoruba. These balls are dried in the sun and sold on markets. Sometimes only dry broken leaves and twigs are sold, not pulped into balls. The dye bath is prepared by soaking crushed balls in hot water, the number of balls depending on the desired intensity of the blue colour. Yoruba women in south-western Nigeria use from 50 balls for a bright blue up to 150 for a blue-black colour. The necessary alkalinity is obtained by adding lye from wood-ash. The solution is left to ferment for 6 - 8 days and the dye bath is then usually ready for the cloth to be steeped in it[
