Medicinal Properties

turmeric flowers

In many research studies, turmeric has been shown to be a treatment for such ailments as gastric ulcerations such as in pylorus ligation, indomethacin, reserpine, and hypothermic-restraint stress; the bacteria Helicobacter pylori infection, a group I carcinogen; peptic ulcers; chronic pain; skin diseases; wounds; digestive ailments; liver conditions; irritable bowel syndrome (IBS); rheumatoid arthritis (RA); osteoarthritis (OA); bursitis; diabetes; obesity; neurologic and psychiatric disorders; strains of Staphylococcus aureus; Salmonella paratyphi; Trichophyton gypseum; Mycobacterium tuberculosis; Alzheimer’s disease; depression; cardiovascular disease; uveitis; ulcerative proctitis; Crohn’s disease; ulcerative colitis; irritable bowel disease; tropical pancreatitis; peptic ulcer; gastric ulcer; idiopathic orbital inflammatory pseudotumor; oral lichen planus; gastric inflammation; vitiligo; psoriasis; acute coronary syndrome; atherosclerosis; diabetic nephropathy; diabetic microangiopathy; lupus nephritis; renal conditions; acquired immunodeficiency syndrome (AIDS); β-thalassemia; biliary dyskinesia; Dejerine-Sottas disease; cholecystitis; chronic bacterial prostatitis; hepatic conditions; chronic arsenic exposure; metabolic syndrome; anxiety; hyperlipidemia; exercise-induced inflammation and muscle soreness; and alcohol intoxication. Oil of turmeric, distilled from the dried rhizome, shows antiseptic properties.

Turmeric has been shown to contain choleretic, antimicrobial, anti-inflammatory, pleiotropic, anti-bacterial, anti-oxidant, pro-apoptotic, chemopreventive, chemotherapeutic, anti-proliferative, wound healing, anti-nociceptive, anti-parasitic, anti-malarial, antifungal, cholesterol-lowering, antifibrotic, antimutagenic, lipotroppic effects, digestive aid, and carminative properties.

Studies have shown that turmeric could possibly reduce the risk for cancer, specifically pancreatic cancer, prostate cancer, and multiple myeloma. It has also been shown to effectively treat some chronic illnesses affecting the eyes, lungs, liver, kidneys, and gastrointestinal and cardiovascular systems.

According to The Arthritis Foundation, name several studies in which turmeric has reduced inflammation. This anti-inflammatory ability might reduce the aggravation that people with arthritis feel in their joints.

Some research stiudies have shown turmeric to be as effective in treating pain as ibuprofen (Advil).

The antioxidant effect of turmeric appears to be so powerful that it may stop your liver from being damaged by toxins. This could be good news for people who take strong drugs for diabetes or other health conditions that might hurt their liver with long-term use.

Curcumin boosts brain-derived neurotrophic factor, linked to improved brain function and a lower risk of brain diseases. One of the main drivers of this process is brain-derived neurotrophic factor (BDNF), which is a type of growth hormone that functions in your brain. Many common brain disorders have been linked to decreased levels of this hormone, including depression and Alzheimer’s disease. Curcumin can increase brain levels of BDNF. By doing this, it may be effective in delaying or even reversing many brain diseases and age-related decreases in brain function. It may also improve memory and make you smarter, which seems logical given its effects on BDNF levels.

Curcumin may help reverse many steps in the heart disease process. Perhaps the main benefit of curcumin when it comes to heart disease is improving the function of the endothelium, which is the lining of your blood vessels. It’s well known that endothelial dysfunction is a major driver of heart disease and involves an inability of your endothelium to regulate blood pressure, blood clotting and various other factors. Several studies suggest that curcumin leads to improvements in endothelial function.

Curcumin has been studied as a beneficial herb in cancer treatment and been found to affect cancer growth, development and spread at the molecular level. Studies have shown that it can contribute to the death of cancerous cells and reduce angiogenesis (growth of new blood vessels in tumors) and metastasis (spread of cancer).

A research study found turmeric extracts are as effective as ibuprofen for the treatment of knee osteoarthritis. The side effects were similar but with fewer gastrointestinal issues in the turmeric extracts group.

Another study states: “Curcumin delivery system is effective in the management of central serous chorioretinopathy. When administered in a bioavailable formulation, curcumin is worth considering as a therapeutic agent for the management of inflammatory and degenerative eye conditions involving activation of retinal microglial cells.”

Additional studies show that curcumin helps protect the kidneys: “these studies attribute the protective effect of curcumin in the kidney to the induction of the master regulator of antioxidant response nuclear factor erythroid-derived 2 (Nrf2), inhibition of mitochondrial dysfunction, attenuation of inflammatory response, preservation of antioxidant enzymes and prevention of oxidative stress. The information presented in this paper identifies curcumin as a promising renoprotective molecule against renal injury.”

Numerous research studies have been performed to show the effectiveness of turmeric as a treatment. These include studies for: colorectal cancer, breast cancer, pancreatic cancer, prostate cancer, multiple myeloma, lung cancer, cancer lesions, head and neck squamous cell carcinoma, inflammatory bowel disease, irritable bowel syndrome, arthritis, uveitis, postoperative inflammation, peptic ulcer, H. pylori infection, idiopathic orbital inflammatory pseudotumor, vitiligo, psoriasis, Dejerine-Sottas disease, Alzheimer’s disease, acute coronary syndrome, atherosclerosis, diabetes, type 2 diabetic nephropathy, diabetic microangiopathy, lupus nephritis, renal transplantation, acquired immunodeficiency syndrome, β-Thalassemia, biliary dyskinesia, gallbladder contraction, recurrent respiratory tract infections, ATT-Induced hepatotoxicity, chronic arsenic exposure, alcohol intoxication and chronic bacterial prostatitis. Many studies are still ongoing.

Biochemical Information

Curcumin is the active ingredient in turmeric.

The main component of the root is a volatile oil, containing turmerone, and there are other coloring agents called curcuminoids in turmeric. Curcuminoids consist of curcumin demethoxycurcumin, 5’-methoxycurcumin, and dihydrocurcumin, which are found to be natural antioxidants (Ruby et al. 1995; Selvam et al. 1995). In a standard form, turmeric contains moisture (>9%), curcumin (5–6.6%), extraneous matter (<0.5% by weight), mould (<3%), and volatile oils (<3.5%). Volatile oils include d-α-phellandrene, d-sabinene, cinol, borneol, zingiberene, and sesquiterpenes (Ohshiro, Kuroyanag, and Keno 1990). There are a variety of sesquiterpenes, like germacrone; termerone; ar-(+)-, α-, and β-termerones; β-bisabolene; α-curcumene; zingiberene; β-sesquiphellanderene; bisacurone; curcumenone; dehydrocurdione; procurcumadiol; bis-acumol; curcumenol; isoprocurcumenol; epiprocurcumenol; procurcumenol; zedoaronediol; and curlone, many of which are specific for a species. The components responsible for the aroma of turmeric are turmerone, arturmerone, and zingiberene. The rhizomes are also reported to contain four new polysaccharides-ukonans along with stigmasterole, β-sitosterole, cholesterol, and 2-hydroxymethyl anthraquinone (Kapoor 1990; Kirtikar and Basu 1993).

Formulas or Dosages

The Arthritis Foundation suggests taking turmeric capsules of 400 to 600 milligrams (mg) up to three times per day for inflammation relief.

Participants in research studies into the use of turmeric for pain relief took 800 mg of turmeric in capsule form each day.

It is important to note that turmeric alone is not easily absorbed into the bloodstream. Adding black pepper, which contains piperine, a natural substance that enhances the absorption of curcumin by 2,000%.

Curcumin is fat soluble, so it may be a good idea to take it with a fatty meal.

For hay fever: 500 mg of curcumin, a chemical in turmeric, has been used daily for 2 months.

For depression: 500 mg of curcumin, a chemical in turmeric, has been taken twice daily, alone or along with 20 mg of fluoxetine daily, for 6-8 weeks.

For high levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia): 1.4 grams of turmeric extract in two divided doses daily for 3 months has been used.

For buildup of fat in the liver in people who drink little or no alcohol (nonalcoholic fatty liver disease or NAFLD): 500 mg of a product containing 70 mg of curcumin, a chemical in turmeric, has been used daily for 8 weeks.

EFor osteoarthritis: Most often, 500 mg of turmeric extract has been taken two to four times daily for 1-3 months.

For itching: 1500 mg of turmeric in three divided doses daily for 8 weeks has been used. Also, a specific product containing turmeric extract (C3 Complex, Sami Labs LTD) plus black pepper or long pepper has been used daily for 4 weeks.

For arthritis: dosages of 8–60 g of fresh turmeric root three times daily have been recommended (Fetrow and Avila 1999).

For dyspepsia: 1.3–3.0 g of turmeric root is recommended.

When 1 or 2 tablets of a standardized turmeric extract were given daily for 8 weeks, the prevalence of irritable bowel syndrome was significantly decreased, as was the abdominal pain/discomfort score
