Turmeric (Curcuma longa)
Dr. med. Heinz Lüscher
The wonder tuber turmeric has been known as a remedy in traditional Chinese medicine and Ayurveda for thousands of years, but has also been very well researched in our latitudes in recent years. The medicinal effects of turmeric (active ingredient curcumin) are very diverse, which is why it can be used very widely.
Where does turmeric come from?
The plant turmeric (lat. name Curcuma longa) originates from tropical and subtropical regions in South Asia. German names are Gelber Ingwer, Safranwurz or Gelbwurz. Although turmeric belongs to the ginger family, it is not identical to the common ginger, even though they look similar at least externally. As with ginger, the rhizome (rootstock) of the plant is used. Turmeric is available fresh as well as dried and powdered.
Turmeric in the kitchen
Turmeric has been called the "golden spice of life" in India for thousands of years and Indian cuisine would be unthinkable without it. Turmeric is the main ingredient of curry and does not taste very hot. Even in our latitudes the yellow root can be found in many shops and can be used in various dishes. But beware: turmeric alone is almost not absorbed in the intestine! When mixed with a little black pepper (active ingredient piperine), the absorption in the intestine is increased several times. A good turmeric powder has therefore always had some pepper added.
The healthy ingredients
In traditional Chinese medicine and Ayurveda, turmeric has been known as a remedy for thousands of years. Meanwhile, numerous studies confirm the versatile properties and effects. The substance that is effective for health is called curcumin. The other components of the root tuber are not important from a medical point of view, even though turmeric contains some vitamins and minerals.
The medicinal effects of turmeric are very diverse
- powerful antioxidant
- inhibits the growth of bacteria, viruses, parasites and fungi
- promotes bile production (-> cholesterol-lowering)
- gentle on the liver
- inhibits the growth of tumours
- can repair damage to DNA
For these reasons curcumin can have a good effect on many different diseases!
Diseases in which turmeric can be used
- Cancer, even in advanced stages with metastases
- Colitis ulcerosa
- Crohn's disease
- Digestive problems, flatulence, stomach ache
Conditionally also helpful for the following complaints:
- Liver damage, hepatitis
- High cholesterol
- Stomach inflammation / Gastritis
- Menstrual cramps
- Macula degeneration (age-related visual impairment)
Turmeric should not be taken at:
- Known gallstones complaints
- Iron deficiency and anaemia
Efficacy in cancer
The best research has been done on the effects against cancer. The following examples should be of particular interest to oncologists:
- Turmeric lowers the Cyclin D1 level
- Turmeric lowers the C-Jun-N-terminal kinase
- Turmeric lowers cyclooxygenase 2 (COX2)
- Turmeric reduces the formation of matrix metalloprotein 9 and MMP 2
- Turmeric reduces the activity of urikinase plasma activator
- Turmeric reduces the phosphorylase kinase
- Turmeric reduces NF-Kappa-B
- Turmeric increases the activity of the protective p53 gene
- Turmeric reduces Bcl2
- Turmeric inhibits the synthesis of EGF (epithelial growth factor)
- Turmeric inhibits HER2 in breast cancer
- Turmeric has many other influences on various enzymes of cancer cells
I have made this list consciously, even if most people do not understand it. Only general practitioners do not usually deal with molecular biological processes in such depth. But oncologists understand every sentence. I only want to show that the cancer inhibiting effects are known and proven. Turmeric is at least equivalent to any chemotherapeutic agent, but has practically no side effects. Together with other vital substances effective against cancer, turmeric is part of the standard therapy in natural cancer treatment.
Why can turmeric be used preventively and acutely for cancer?
The consequences of the above-mentioned activities of the enzymes lead to increased apoptosis (natural cell death) in cancer cells, delaying the formation of new blood vessels, reducing inflammation and slowing down the invasion of healthy tissue. Even metastasis is hindered. Turmeric is effective against practically every type of tumour.
Effectiveness in inflammatory bowel diseases
The two most common chronic inflammatory bowel diseases are ulcerative colitis and Crohn's disease. While ulcerative colitis affects only the large intestine, Crohn's disease can affect the entire digestive system from the oral cavity to the rectum. The cause of these diseases is not known, it is a kind of misdirected immune reaction. However, I personally am convinced that in many cases there is a food intolerance behind it, which could be well treated. In orthodox medicine there is only one invasive therapy with many side effects and moderate success. Both diseases are treated with high doses of cortisone, later on with immunosuppressive drugs and finally only one operation remains.
Patients suffering from Crohn's disease in particular suffer from a serious lack of almost all important vital substances because the inflamed intestine can no longer absorb these substances. An anti-inflammatory effect of the intestinal cells with turmeric, together with other anti-inflammatory vital substances and a detoxification by the volcanic rock clinoptilolite (a so-called intestinal sanitation), have an excellent effect on all inflammatory diseases of the intestine. In addition to its anti-inflammatory and antioxidant effects, turmeric also has a positive influence on the intestinal flora, which in itself is a comprehensive effect on overall health. Because today we know that a well functioning intestinal flora is the prerequisite for health and healing. Thus turmeric can also be used for digestive disorders, flatulence, etc.
Efficacy in Alzheimer's disease
It is a fact that far fewer Indians suffer from Alzheimer's than Western Europeans or Americans. This dreaded disease is increasing alarmingly. Today, 10 % of 65-year-olds and around 30 % of those over 80 are affected. The costs for Alzheimer patients are higher than for heart or cancer patients and are gradually getting out of hand. Any remedy that helps is therefore highly welcome.
Because of the numerous positive effects of turmeric and the fact that the active ingredient curcumin can easily cross the blood-brain barrier and therefore also shows its antioxidant and anti-inflammatory effects in the brain, it was decided to study the effects on Alzheimer's disease.
It has been shown that curcumin is able to mobilise and break down so-called plaques (beta-amyloid deposits) in the brain that are related to Alzheimer's disease. There seems to be an improvement even in Alzheimer's patients with turmeric in need of care. It has not yet been conclusively proven that turmeric can prevent Alzheimer's, but it certainly has a noticeable positive effect and should be used more often together with other vital substances (for example Q10, omega-3 and phosphatidylserine) to prevent Alzheimer's.
Dosage of encapsulated turmeric
For most diseases, 3-4 capsules (e.g. turmeric vida from kingnature) should be taken daily with meals throughout the day. For prevention 2 capsules are sufficient. There are many offers on the market. It is essential to ensure that it is a high quality product from organic farming and with a high curcumin content.
