Natural gum consisting of the dried sap of Astragalus species
Astragalus gummiferA dish of Tragacanth
Tragacanth is a natural gum obtained from the dried sap of several species of Middle Easternlegumes of the genus Astragalus, including A. adscendens, A. gummifer,[1]A. brachycalyx,[2][3] and A. tragacantha. Some of these species are known collectively under the common names "goat's thorn" and "locoweed". The gum is sometimes called Shiraz gum, shiraz, gum elect or gum dragon.[4] The name derives from the Greek words tragos (meaning "goat") and akantha ("thorn"). Iran is the biggest producer of this gum.
Gum tragacanth is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides obtained from sap that is drained from the root of the plant and dried. The gum seeps from the plant in twisted ribbons or flakes that can be powdered. It absorbs water to become a gel, which can be stirred into a paste. The major fractions are known as tragacanthin, highly water-soluble as a mucilaginous colloid, and the chemically related bassorin, which is far less soluble but swells in water to form a gel. The gum is used in vegetable-tanned leatherworking as an edge slicking and burnishing compound, and is occasionally used as a stiffener in textiles. The gum has been used historically as a herbal remedy for such conditions as cough and diarrhea. Powders using tragacanth as a basis were sometimes called diatragacanth.[5] As a mucilage or paste, it has been used as a topical treatment for burns. It is used in pharmaceuticals and foods as an emulsifier, thickener, stabilizer, and texturant additive (E number E413). It is the traditional binder used in the making of artists' pastels,[6] as it does not adhere to itself the same way other gums (such as gum arabic) do when dry. Gum tragacanth is also used to make a paste used in floral sugarcraft to create lifelike flowers on wires used as decorations for cakes, which air-dries brittle and can take colorings. It enables users to get a very fine, delicate finish to their work. It has traditionally been used as an adhesive in the cigar-rolling process used to secure the cap or "flag" leaf to the finished cigar body.[7]
In the Middle East, and in Turkey in particular, gum tragacanth is used in paper marbling to make size on which to float and shape the pigments, just as carrageenan is used in the West.
Gum tragacanth is also used in incense-making as a binder to hold all the powdered herbs together. Its water solubility is ideal for ease of working and an even spread, and it is one of the stronger gums for holding particles in suspension. Only half as much is needed, compared to gum arabic or something similar.[8][9]
As food
It is common in Indian cuisine as "Goond Kateera" (also spelled as "Gond Katira" - Hindi: गोंद कतीरा, Urdu: گوند کتیرا). "Goond" means "glue" or "tree sap" in Hindi, so that would mean "tree sap of Kateera". A common dish that uses it is the Jammu and Kashmir cuisine's special sundh.[10][11]
Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion and plasticizers, silicone oils, defoamers, stabilizers, or metal soaps. Most acrylic paints are water-based, but become water-resistant when dry. Depending on how much the paint is diluted with water, or modified with acrylic gels, mediums, or pastes, the finished acrylic painting can resemble a watercolor, a gouache, or an oil painting, or it may have its own unique characteristics not attainable with other media.
A pastel is an art medium that consist of powdered pigment and a binder. It can exist in a variety of forms, including a stick, a square, a pebble, or a pan of color, though other forms are possible. The pigments used in pastels are similar to those used to produce some other colored visual arts media, such as oil paints; the binder is of a neutral hue and low saturation. The color effect of pastels is closer to the natural dry pigments than that of any other process.
Guar gum, also called guaran, is a galactomannan polysaccharide extracted from guar beans that has thickening and stabilizing properties useful in food, feed, and industrial applications. The guar seeds are mechanically dehusked, hydrated, milled and screened according to application. It is typically produced as a free-flowing, off-white powder.
Gouache, body color, or opaque watercolor is a water-medium paint consisting of natural pigment, water, a binding agent, and sometimes additional inert material. Gouache is designed to be opaque. Gouache has a long history, having been used for at least twelve centuries. It is used most consistently by commercial artists for posters, illustrations, comics, and other design work.
Incense is an aromatic biotic material that releases fragrant smoke when burnt. The term is used for either the material or the aroma. Incense is used for aesthetic reasons, religious worship, aromatherapy, meditation, and ceremony. It may also be used as a simple deodorant or insect repellent.
Watercolor or watercolour, also aquarelle, is a painting method in which the paints are made of pigments suspended in a water-based solution. Watercolor refers to both the medium and the resulting artwork. Aquarelles painted with water-soluble colored ink instead of modern water colors are called aquarellum atramento by experts. However, this term has now tended to pass out of use.
Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch and glycogen. Dextrins are mixtures of polymers of D-glucose units linked by α-(1→4) or α-(1→6) glycosidic bonds.
Scott Douglas Cunningham was an American writer. Cunningham is the author of several books on Wicca and various other alternative religious subjects.
Sugar candy is any candy whose primary ingredient is sugar. The main types of sugar candies are hard candies, fondants, caramels, jellies, and nougats. In British English, this broad category of sugar candies is called sweets, and the name candy or sugar-candy is used only for hard candies that are nearly solid sugar.
A binder or binding agent is any material or substance that holds or draws other materials together to form a cohesive whole mechanically, chemically, by adhesion or cohesion.
Encelia farinosa, is a common desert shrub of the southwestern United States and northern Mexico. It has a variety of historical uses.
A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in paints, inks, explosives, and cosmetics.
A gel pen uses ink in which pigment is suspended in a water-based gel. Because the ink is thick and opaque, it shows up more clearly on slick surfaces than the typical inks used in ballpoint or felt tip pens. Gel pens can be used for many types of writing and illustration.
Methyl cellulose is a compound derived from cellulose. It is sold under a variety of trade names and is used as a thickener and emulsifier in various food and cosmetic products, and also as a bulk-forming laxative. Like cellulose, it is not digestible, non-toxic, and not an allergen. In addition to culinary uses, it is used in arts and crafts such as papier-mâché and is often the main ingredient of wallpaper paste.
Commiphora myrrha, called myrrh, African myrrh, herabol myrrh, Somali myrrhor, common myrrh, is a tree in the Burseraceae family. It is one of the primary trees used in the production of myrrh, a resin made from dried tree sap. The tree is native to the Arabian peninsula and to Africa. It is called 'mur' (المر) in Arabic, meaning bitter. It famously comes from Mecca, so it is called 'Mur Makki'.
Hairstyle products are used to change the texture and/or shape of hair.
Gum copal is a resin produced by the sap of forest tree in the genus Daniellia. Due to common impurities and differences in regions, gum copal ranges in color from black to yellow to white. Gum copal, along with ivory and slaves, was a significant export from East Africa in the 19th century. It can have an appearance similar to amber and may be mistaken for it. Unlike amber, gum copal is usually only 100–1,000 years old and it has not yet fossilized.
Astragalus brachycalyx, the Persian manna or manna, whose name is derived from the Greek ‘brachy’ meaning short, and ‘calyx’ referring to the sepal of the flower, is a species of legume commonly found on rocky mountain slopes in western Asia, from western Iran and northern Iraq to Turkey, and is commonly used as a source of gum tragacanth.
Astragalus gummifer, is a small woody evergreen shrub, with a typical height and spread of 30 cm at maturity, indigenous to western Asia, specifically Iran, Iraq and Turkey. This nitrogen fixing plant bears hermaphroditic flowers, which are bee-pollinated. It has many medical, culinary, and material uses.
