Botanical Name – Morus alba (florum)
Chinese Name – SANG YE
English Name – Mulberry Leaf
Tincture made by a process of hydro-ethanolic percolation, with a ratio of 1 part Mulberry Leaf to 3 parts liquid. Liquid comprises of 75% water and 25% sugar beet derived ethanol.
Morus alba, known as white mulberry, is a fast-growing, small to medium-sized mulberry tree which grows to 10–20 m tall. It is generally a short-lived tree with a lifespan comparable to that of humans, although there are some specimens known to be over 250 years old.
The species is native to northern China, and is widely cultivated and naturalised elsewhere.
The white mulberry is widely cultivated to feed the silkworms employed in the commercial production of silk. Its berries are poisonous when unripe, but are otherwise edible.
Medicinal Action and Uses
Antispasmodic – An injection of an extract of the leaves, followed by internal dose of the sap (mixed with sugar), has been shown to be effective as a treatment for elephantiasis (a parasitic infection resulting in extreme swelling in the arms and legs) and tetanus (lockjaw), an infection characterized by muscle spasms.
Diaphoretic – White Mulberry leaves induce perspiration. So can be used to treat a fever.
Expectorant – The leaves of white mulberry have expectorant properties and can be helpful in expelling mucus caused by respiratory tract infections. It is also used in the treatment of colds, coughs and influenza.

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 Morus alba (florum) / SANG YE / Mulberry Leaf 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 Morus alba (florum) / SANG YE / Mulberry Leaf Tincture is filtered and then stored in bulk containers, before being bottled in smaller 250ml, 500ml and 1000ml quantities.
