Rubia Cordifolia which is also called manjistha or Indian Madder belongs to the family Rubiaceae. It is a branched climber with small, greenish white flowers that are arranged in a cluster of rounds, followed by fleshy, purple fruits.
Manjistha is a rich source of anthraquinones responsible for its traditional, phytochemical, and pharmacological activities. This plant grows well in hilly districts, and the roots are known for their medicinal values.
Manjistha is one of the most valuable herbs in Ayurveda. Charak (born in 300 BC) was one of the principal contributors to Ayurveda. He categorized this medicinal herb as varnya (for the enhancement of skin complexion), jvarahara (anti-pyretic), visaghna (a detoxifier) and a rasayana (rejuvenator). Manjistha is probably the best blood-purifying herb in the indigenous system of medicine.
It cools and detoxifies the blood, dissolves obstructions in blood flow and removes stagnant blood. We at Nature’s Laboratory produce various products of Rubia cordifolia, such as manjishtha root tincture and manjishtha root cut.
What is a Tincture?
A herbal tincture is a concentrated extract of one or more herbs. The liquid in a tincture is a combination of alcohol and water. A tincture must contain at least 20% alcohol for preservation purposes. Alcohol concentrations tend to vary between 20% and 60%, but can be as high as 90% in some circumstances. At Herbal Apothecary we generally produce tinctures with alcohol concentrations of 25% - 45%. We use ethanol derived from sugar beat.
How Is A Tincture Made?
To produce the Rubia Cordifolia / Manjistha we combine a quantity of herb with a proportional amount of liquid. Depending on the herb and the strength of tincture required this ratio can be 1:2, 1:3 or 1:4. The herb, alcohol and water is placed in a production vessel suitable for the size of the batch.
Traditionally, tinctures have been made by a process of maceration. This is where the herb sits in the liquid and over a period of time the plant cells break down. This allows the plant matter to be released into the liquid. Occasionally the producer might agitate the mixture to help the process along.
At Herbal Apothecary we have spent decades improving our tincture production processes. We use a system called Hydro-Ethanolic Percolation. Percolation is where liquid slowly passes through the herb, from top to bottom. In our case, the liquid is not simply passed through the herb once and then collected. Instead, it is continually cycled through the herb. Hydro-Ethanolic Percolation is a combination of maceration and traditional percolation. The circulation of liquid through a spray head agitates the herb, helping the key chemical compounds to be released into the liquid.
Our production vessels are primarily stainless steel. We use low voltage (24v) pumps to circulate the liquid. We have also developed a system of float switches and relays. These ensure the pumps only activate when an adequate level of liquid is present in the sump at the bottom of the vessel. It can take some time for the liquid to filter through the herb.
We produce most of our tinctures using dried herbs, although we sometimes use fresh. It's important that the size of the pieces of herb in the production vessel are small enough for the alcohol to thoroughly penetrate. No prior processing is required for flowers and leaves which are smaller and more delicate. However, for roots, bark and berries which tend to be tougher and larger we use herbs which are diced up into small pieces. This ensures that the maximum amount of plant material can be extracted into the liquid.
The manufacturing process takes 7 days to complete. Once the process is finished, the herb is pressed to extract every last drop of precious liquid. The Rubia Cordifolia / Manjistha is filtered and then stored in bulk containers, before being bottled in smaller 250ml, 500ml and 1000ml quantities.

At Herbal Apothecary we are committed to research - we want to provide a robust evidence base for the products we produce. As a result we review our manufacturing systems and processes in order to ensure we're making best use of the raw ingredients.
Cut herbs are herbs which have been harvested and then cut into smaller pieces, suitable for further processing. Cut herbs like Rubia Cordifolia / Manjistha can be used to produce tinctures or fluid extracts. They can also be used in herbal teas and infusions.
