Indigo in water in a jar for laundry bluing

A tiny amount of indigo with water gives enough laundry bluing for several washes. So what you see is the laundry blue concentrate which will do several washes.

Whiten your whites with indigo. Indigo is the original laundry bluing. Over time bleached white textile take on a yellow tinge, especially when washed with hard water. Use indigo as a natural optical enhancer to whiten whites. Bluing can be achieved with either powder or blocks.

For whitening in the washing machine

With powder – place 1/4 teaspoon of powder in a jar or water and shake or stir to mix. Add 1/5 to 1/4 of the blue mixture into the fabric conditioner compartment of your washing machine.

For whitening hand washed items

Or if washing by hand, add less of the blue mixture into the final rinse water (because the load size is smaller). Agitate the clothing well or soak for a few minutes. You can also use an indigo block when hand washing – place the block in a cotton bag or old sock and dip in and out of the warm rinse water until the desired shade is reached. Then add the clothing to the rinse water as before. All the indigo laundry blue block to dry and store carefully.

Next time you use the laundry blue you have made in a jar, shake it or stir it to disperse the indigo again in the concentrate.

How Natural Spa Supplies Blue Indigo is Made

Harvesting takes place through the summer from June until September as individual ripened leaves are collected. After harvesting, the plant is washed to remove soil, at this stage already, the purity of the indigo is notably increased. The leaves are crushed into a pulp with a stone mill, and the paste is then gradually dried in a barn until it is judged ready to roll by hand into fist sized balls, known as ‘cocagnes’. The cocagnes are placed on racks in the curing barn to cure again and to continue drying for between one and two months. At the end of this curing process, the cocagnes are known as ‘pastel de Cocagne’

Finally, to prepare the dye, the balls are crushed into a powder which is mixed with water and goat and camel urine for the main fermentation in which the purity of the dye will be enhanced further! The mixture is agitated to control the temperature and to bring about a permanent change. The pigmented sediment is allowed to dry again and then it is broken into blocks or cubes. At this point the cubes can be powdered again. By using these ‘slow’ and traditional methods, it means that no caustic chemicals are used in the production of our indigo and that it is safe for use on the skin and hair. Eventually the indigo is allowed to form a sediment and  dried.

Indigo Chemistry

Indigotin is insolubale in water, so an alkaline and  reducing agent is added to the dye vat containing the blue indigo powder to reduce the indigotin (removing one oxygen molecule). The fibres can absorb the indigo while it is in the reduced state and when the dyed fibre is exposed to the air, the indigo white oxidizes and turns blue and insoluble again.

Blocks or Powder?

We supply the indigo in either block or powder form. If you choose blocks we will need to send you several blocks to make up the correct weight.

Shelf Life of Natural Blue Indigo Powder

If stored under optimal conditions, the shelf life is 10 years.


Depending on the quantity ordered, we supply the indigo in paper or glass jars.


Our indigo is made for Natural Spa Supplies in Morocco using time honoured methods. This is the genuine Indigo – which has been fermented in goat and camel urine! We have carried on this method not just to preserve human heritage but because in this way, we can obtain the purest indigo powder without the use of industrial chemicals.

While the production level is too small to gain organic status and the indigo plant does not need fertilizers or chemical treatments, in fact indigo plants are leguminous and use soil bacteria to fix nitrogen from the air. In that way indigo planting leaves the soil enriched with nutrients to help other crops to grow well. Indigo plants are used in interplanting and intercropping schemes as well as a cover crop to enrich the soil.
