Digestive troubles and diseases significantly alter our quality of life
Digestive troubles, or more serious diseases, are health ailments that each one of us will encounter at least once in our lifetime. Notwithstanding digestive cancers that have been known for a long time, new diseases derived from our modern ways of living are becoming an increasingly greater threat to our quality of life.
Irritable bowel syndrome (IBS), one of the most common disorders seen by physicians, is the most common functional gastrointestinal (GI) disorder with worldwide prevalence rates ranging generally in the range of 10–15%.
Inflammatory bowel diseases, mainly Crohn’s disease and ulcerative colitis, are increasing, even in newly industrialised countries, to reach 0.3% of the global population. The increasingly publicised liver disease, non-alcoholic fatty liver disease (NAFLD), also known as the soda disease, has a worldwide prevalence of close to 25%.
Turmeric (Curcuma longa) is a well-known spice from India that has received wide interest from both the medical and scientific worlds. Turmeric is a rhizomatous, herbaceous perennial plant of the ginger family and has been used in Ayurvedic medicine in India for more than 2500 years to treat a variety of ailments.
The orange polyphenolic active principles are composed of three primary curcuminoids: curcumin, demethoxycurcumin (DMC) and bisdemethoxycurcumin (BDMC), comprising around 70–80, 15–20 and 2.5–10% of the total curcuminoids, respectively.
Vidya Herbs’ turmeric extracts are branded under the name Puremeric and are characterised by HPLC contents of the three curcuminoids, an isotopic 14C analysis and DNA testing to prove the natural origin and the absence of synthetic substitution. The botanical variety is guaranteed by a botanist and complete traceability is ensured from the “field to the product.”
Turmeric has been used for centuries for a wide range of ailments, mostly because of its anti-inflammatory and antioxidant effects. Curcumin may be considered as a remedy for liver troubles, IBS, IBDs, NAFLD, NASH and even cancers.
One of the main sources of digestive ailments is stress, which is well-known to generate acid secretion and, ultimately, ulcers. With an animal model of stress, curcumin showed dose-dependent gastroprotective properties. These activities are explained by the reduced expression of proinflammatory factors.1
A healthy liver is necessary for the maintenance of good health because this organ has many important functions, including helping to digest food, processing and distributing nutrients, and also metabolising xenobiotics and endogenous molecules. Oxidative stress may alter liver function and cause liver diseases.
Using an animal model of high-fructose NAFLD, it has been shown that curcumin is effective in hepatic lipogenesis, mitochondrial dysfunction, inflammation and insulin resistance, and therefore is effective as a new natural treatment for NAFLD.2
The third organ that could benefit from curcumin's antioxidant properties is the gut. According to animal experiments, curcumin can regulate the gut’s microbiota composition.
Human trials that try to elucidate this regulation generally shed light on the complex pharmacology of curcumin and the complexity of those human intervention studies that attempt to study the effects of these potentially powerful herbal medicines.
IBDs are highly complex diseases that correlate gut microbiota composition with inflammatory status. An animal model of colitis-associated colorectal cancer showed that curcumin was able to alter the microbial ecology and reduce inflammation.3
The available data from published in vitro and in vivo studies suggest that curcumin could be a beneficial complementary supplement for the entire digestive tract. Nevertheless, owing to the physicochemical properties of curcuminoids, a new form is required to improve its solubility, absorption and bioavailability. To remedy the situation, Vidya Herbs developed a naturally bioavailability enhanced curcuminoid concentrate: Vi-Active.
To compare Vi-Active with a standard turmeric extract, both standardised in 95% curcuminoids, a randomised clinical study was done on 24 volunteers.
In a two-period design, 12 healthy subjects were included in each group. Two single doses (500 mg) were administrated with a washout period of 7 days between each consumption period and the curcumin plasma concentration was monitored by LC-MS/MS. At the maximum absorption time, the curcumin plasma concentration in the Vi-Active group was found to be more than 2.2 times higher than in the standard turmeric group.
Boswellia serrata is native to much of India, especially the Punjab region. In Ayurvedic medicine, some parts of Boswellia bark are peeled away, yielding a gummy oleoresin that has been used for hundreds of years in the treatment of arthritis.
3-O-Acetyl-11-keto-beta-boswellic acid (AKBA) is the most active component of Boswellia extract and has been proven to be a potent inhibitor of 5-LOX, which is a key enzyme in the biosynthesis of leukotrienes from arachidonic acid in the cellular inflammatory cascade.
Extracts from the oleoresin of Boswellia serrata are characterised by their content of four pentacyclic triterpene acids, with beta-boswellic acid being the major constituent. Vidya offers extracts from 30% to 90% boswellic acids or with a standardised 30% AKBA content. All our Shallaki extracts are completely traceable with botanical certificate of origin and comply with the highest standards of quality.
Using an animal model on gastric ulcers induced by several molecules, the protective effect of boswellic acid was demonstrated. The effect seems to be linked to an increase in gastric mucosal resistance, the local synthesis of cytoprotective prostaglandins and the inhibition of the leukotriene synthesis.4
Boswellic acid could also be useful for NAFLD. Treated animals (rats with NAFLD, induced by a high-fat diet) showed an improved insulin sensitivity, a reduction in liver index and an ameliorated expression of thermogenesis-related mitochondrial uncoupling protein-1 and carnitine palmitoyl transferase-1 in white adipose tissues at the cellular level.5
The gut is also an organ that could benefit from Boswellia, which may help to alleviate functional troubles by improving motility, inhibiting diarrhoea without constipation and could also treat more serious troubles or diseases.6
One of the interest areas of Boswellia extract is its ability to preserve the intestinal barrier from oxidative and inflammatory damage as it occurs in IBDs. Boswellia’s antioxidant activity is the mechanism involved in the physiologic maintenance of the integrity and function of the intestinal epithelium.7 The epithelial barrier is dramatically involved in IBDs and Boswellia extracts also present benefits for this kind of disease.8
Boswellia extracts and, more specifically, acetyl-11-keto-ß-boswellic acid (AKBA) could present potential interest in cancers, such as by inhibiting gastric carcinoma growth or by inhibiting growth and metastasis of colorectal cancer.9,10
With these two types of high-quality herbal extracts, founded on Ayurvedic tradition and modern science, natural and efficient formulations for digestive health could be offered to consumers reaching for alternative solutions to their health troubles.
