Rhizome, i.e. underground shoot of Curcuma longa, see also turmeric.

MPC monograph: traditional use: digestive complaints, functional disorders of the biliary system, dyspeptic complaints. Curcuma longa rhizoma and Javanese turmeric (see under turmeric): traditional use for digestive complaints, bloating, slowed digestion and flatulence.

Empirical medicine: inflammatory diseases, functional disorders of the gallbladder and bile ducts.

Studies have found an effect comparable to that of ibuprofen on symptoms of knee osteoarthritis (Gupte PA et al. 2019), and initial studies also indicate an improvement in memory, fatigue and resilience (Cox KH et al. 2015), as well as a reduction in beta-amyloid levels in the blood (DiSilvestro RA et al. 2012), in addition to a reduction in cholesterol levels, especially LDL. There are also studies on improving colitis activity, inflammatory parameters and quality of life in ulcerative colitis (Sadeghi N et al. 2020).

The curcuma rootstock contains 3 to 12% essential oil, including sesquiterpenes, xanthorrhizole, and beta-curcumen. The main active ingredient of turmeric is curcumin. Other ingredients are dicinnamoylmethane derivatives, ferulic acid, caffeic acid and caffeic acid derivatives.

Curcumae longae rhizoma has cholekinetic, choleretic, antiphlogistic and spasmolytic effects. It also possesses antitumor, antiviral, antioxidant, hepatoprotective, and antihepatotoxic effects.

Due to the analgesic, antiphlogistic effect, studies also show positive effects in rheumatoid arthritis.

Turmeric is traditionally used as a spice and colorant in food.

Medicinally, curcuma rootstock is used for dyspeptic complaints, mild liver-gallular dysfunction, pain and inflammation due to rheumatoid arthritis diarrhoea, skin diseases, amenorrhoea, dysmenorrhoea and peptic ulcers.

The mean daily dose of the drug is between 1.5 and 3 g. It is used as a galenic preparation for ingestion.

Monopreparation from C.longa:

^Curcu-Truw® capsules (ED 81mg) 1-0-1 capsule/day

The curcuma rootstock should not be confused with the Canadian turmeric (Hydrastis canadensis L.).

Curcuma rootstock and the Javanese turmeric are derived from almost related plant species and have almost identical ingredients, properties and areas of application.
