Rhubarb
Rhubarb root (Rheum officinale and Rheum palmatum) refers to the dried underground parts of these medicinal rhubarb species, rather than the culinary stalks commonly used in pies and desserts. It has a distinctive earthy, bitter and astringent character, with a long history in traditional herbal preparations and applications involving botanical ingredients.
At Austral Herbs, we supply certified organic rhubarb root in a coarse-cut format and two powdered variants, giving buyers a choice of botanical species and ingredient formats for their intended applications.

Rhubarb Specifications & Characteristics

What is Rhubarb?
Rhubarb root is a botanical ingredient obtained from the underground parts of medicinal rhubarb species, including Rheum officinale and Rheum palmatum. These large-leaved plants have a long history of cultivation and use in traditional Chinese herbal practice, particularly in regions of China and surrounding areas.
When dried and cut, rhubarb root typically has a dark brown exterior and an amber-toned interior, with an earthy, bitter and astringent flavour. It is distinct from culinary rhubarb, which is cultivated for the edible stalks commonly used in pies, jams and desserts.
Rhubarb root has been used in Chinese herbal medicine for more than a thousand years, traditionally prepared in decoctions by simmering the root in water. It later became known in European herbal practice, where its botanical characteristics and traditional applications also attracted interest.[1]
At Austral Herbs, we supply certified organic rhubarb root in coarse-cut and powdered formats, with different botanical species available to meet specific ingredient requirements. Our rhubarb is processed in a HACCP-certified facility, with formats suited to traditional herbal, botanical and specialist formulation applications.
Traditional Uses of Rhubarb
Rhubarb root has a long history in traditional Chinese herbal medicine, particularly for digestive health. It also contains natural plant compounds that have attracted scientific interest, although evidence supporting specific health benefits remains limited.
Traditionally Associated With Digestive Health
Rhubarb root, known as Da Huang, has been used for centuries in traditional Chinese medicine in preparations associated with bowel function and digestive complaints. These historical applications have attracted scientific interest, although traditional use does not establish proven health benefits from consuming dried rhubarb root.[1]
Natural Plant Compounds and Their Traditional Uses
Rhubarb root contains compounds called anthraquinones, including emodin and rhein, which have been studied for their potential effects on digestion. Some are associated with laxative activity, although more research is needed to understand their benefits and safety.[1][2]
Tannins and Traditional Astringent Uses
Rhubarb root contains tannins and other natural compounds that contribute to its bitter, astringent taste. These characteristics have historically been valued in herbal preparations, although research has not established specific health benefits from consuming dried rhubarb root.[1] For broader historical context, explore our guide to dried herbs and their traditional uses.

What Industries Can Rhubarb Be Used In?
Rhubarb root is recognised for its earthy, bitter and astringent characteristics, as well as its history in traditional herbal preparations and botanical applications. The available cut and powdered formats provide different options for buyers sourcing medicinal rhubarb ingredients.
Tea
Tea blenders may use rhubarb root as a base note in traditional herbal blends with bitter and earthy flavour profiles. Its distinctive characteristics can influence the sensory profile of these formulations, with the resulting intensity depending on the quantity used and preparation method. The 10–20 mm cut may suit preparations where larger root pieces are preferred for separation after steeping or simmering, while powdered variants offer a finer ingredient format.
For more information, see our notes on crafting teas with dried botanicals.
Beverage Manufacturing
Rhubarb root’s bitter and astringent flavour profile may appeal to beverage developers exploring botanical extracts and specialist formulations. Powdered rhubarb root offers a finer ingredient format for botanical preparations, while cut root may be considered for processes involving steeping or simmering.
For broader ingredient sourcing considerations, see our guide to sourcing quality dried herbs and spices for beverage manufacturers.
Wellness & Naturopathy
Known as Da Huang in traditional Chinese herbal medicine, rhubarb root has a long history in herbal preparations. Its cut and powdered formats offer options for specialist formulations, while organic certification provides supporting documentation for buyers seeking certified ingredients.

Food Manufacturing
Rhubarb root has a distinctive bitter and earthy flavour that may interest manufacturers exploring specialist botanical ingredients. Medicinal rhubarb root differs from culinary rhubarb stalks, and its suitability for use in food products must be assessed against applicable Australian food regulations before use.

Creative
Rhubarb root may be explored as an ingredient in botanical dye and craft preparations, including applications involving textiles and paper. Results can vary depending on the preparation method and materials used. Cut root provides larger pieces that may be easier to remove after extraction, while powder offers a finer format for exploring botanical inks, papermaking and other creative applications.

What is the difference between rhubarb root and rhubarb stalks?
They are different parts of the same plant, sold for different purposes. The stalk is the pink stem eaten as a vegetable in pies and jams.[3] The root is the woody underground part, dried for herbal blends and beverages. At Austral Herbs, we only supply the dried root.
What is the difference between Chinese and Turkish rhubarb?
They are two separate species. Chinese rhubarb is Rheum officinale and Turkish rhubarb is Rheum palmatum. Both are medicinal rhubarb species with a history of use in traditional herbal preparations. Always check the botanical name when selecting a specific rhubarb ingredient.
Is rhubarb root the same as Da Huang?
Yes. Da Huang is the traditional Chinese name for dried rhubarb root, and it usually refers to Rheum officinale or Rheum palmatum, the two species we supply.[1] If a formulation specifies Da Huang, check the required botanical species and ingredient format before selecting from our Official or Turkish Rhubarb products.
Should I use cut or powdered rhubarb root for extraction?
Cut root suits slow water extraction, and powder suits almost every other application. The 10-20 mm cut holds together through a long simmer and leaves the liquid clear, which is why decoctions and syrups typically use this specific cut. Powder on the other hand, generally allows faster extraction and disperses evenly, so it is ideal for capsules, dry blends and infusions.
How should rhubarb root be stored?
Store rhubarb root in a sealed container in a cool, dark and dry place as exposure to moisture may cause clumping or affect the quality of the dried ingredient, particularly in powdered formats. An airtight container stored away from heat, moisture and direct sunlight can help maintain product quality.

Pairs Well With
Ginger
Ginger adds warming spice that can balance rhubarb root’s earthy, astringent character. The pairing may suit botanical beverages, bitters and warming herbal blends.
Liquorice Root
Liquorice root contributes natural sweetness that can soften rhubarb root’s bitterness and astringency. Together, they may suit complex herbal tea and botanical formulations.
Peppermint
Peppermint brings a cool, fresh top note that contrasts with rhubarb root’s heavier flavour. It can make robust herbal blends feel lighter and more aromatic. For more on its formats and applications, see our guide to peppermint as a herbal ingredient.
Marshmallow Root
Marshmallow root has a much milder flavour and can add softness to blends containing more assertive rhubarb root. The pairing is commonly found in multi-botanical tea and wellness formulations.
Angelica
Angelica root adds an aromatic, bittersweet flavour that complements rhubarb root in bitters-style and botanical beverage formulations.
