Ziziphus jujuba, commonly called jujube, red date, Chinese date, Korean date, or Indian dateis a species of Ziziphus in the buckthorn family (Rhamnaceae).
It is a small deciduous tree or shrub reaching a height of 5–12 metres, usually with thorny branches. Its precise natural distribution is uncertain due to extensive cultivation, but is thought to be in southern Asia, between Lebanon, northern India, and southern and central China, and possibly also south eastern Europe.
The freshly harvested, as well as the candied dried fruit, are often eaten as a snack. Smoked jujubes are consumed in Vietnam and are referred to as black jujubes. Both China and Korea produce a sweetened tea syrup containing jujube fruit in glass jars, and canned jujube tea or jujube tea in the form of teabags.
Medicinal Action and Uses
Circulatory – The fruit regulates the circulation. The jujube fruit is a rich source of both iron and phosphorous, which are key ingredients in the red blood cells. By increasing your iron and phosphorous intake with jujube fruit, you can increase blood flow, thereby oxygenating your organ systems more effectively.
Digestive – Jujube fruits are also linked to improving digestive processes within the body. This is mainly attributed to its fibre content.
Immunostimulant – Jujube is able to benefit the immune system in many different ways, namely due to its high antioxidant content, including vitamin C, vitamin A, and various organic compounds and acids. These antioxidants are able to neutralize free radicals, which are responsible for many chronic diseases and illnesses within the body. The saponins and alkaloids found in jujube fruit have been directly linked with purifying the blood and eliminating harmful toxins from the body’s systems
Nervine – Jujube has been proven to have certain anxiolytic and soothing effects on the body. The fruit can have an impact on your hormonal levels and induce a calm, relaxed sensation through your mind and body.
Topical uses – Jujube juice and extract have been used topically to treat various skin irritations and inflammations, including psoriasis, eczema, and acne.

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 Ziziphus jujuba syn. spinosa / DA ZAO / Sour Chinese Date (Fruit) Tincture 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 Ziziphus jujuba syn. spinosa / DA ZAO / Sour Chinese Date (Fruit) Tincture is filtered and then stored in bulk containers, before being bottled in smaller 250ml, 500ml and 1000ml quantities.
