9 Remedies Inhibited Non Alcoholic Fatty Liver Disease (NAFLD), According to PubMed Literature

By Kyle J. Norton

Non-alcoholic Fatty Liver Disease is a condition of the fatty liver diseases chracterized by accumulated of fat in the liver, not caused by abusive alcohol consumption.

Nonalcoholic fatty liver disease (NAFLD) is emerging as a widespread condition in US, approximately 30% of adult population are obese.

Finding the natural treatments for less or no side effects has become urgency in many scientific community including researchers in Universities. 

Alternative medicines for the treatment of NAFLD have been proven with many successful histories of controlling disease with no or less side effects.

1. Turmeric 

Turmeric is a perennial plant in the genus Curcuma, belongings to the family Zingiberaceae, native to tropical South Asia.

Turmeric has long been used in herbal medicine in treating numbers of disease.

Today its curcuminoid, curcumin has attracted interests from researchers in many parts of the world.

Curcumin, as an antihyperlipidemic agents, has been found to lower the “bad cholesterol” low density lipoprotein (LDL), and increase high density lipoprotein (HDL) of which reduce the risk of fat accumulated in the tissues in the liver. 

Excessive fat deposited in hepatocytes may cause metabolic imbalances, inducing Non- alcoholic fatty liver diseases. 

In the support of the above, the water-soluble curcumin derivative was tested for its efficacy against steatohepatitis which is an inflammation of the liver with concurrent fat accumulation in liver, the derivative not only significantly alleviated fibrosis but also decreased the grade of liver steatosis. 

2. Hawthorn

Hawthorn is a shrubs and trees of the genus Crataegus, belongings to the family Rosaceae, native to temperate regions of the Northern Hemisphere in Europe, Asia and North America.

 The herb has been used in traditional medicine to treat heart disease and symptoms of heart diseases such as irregular heartbeat, high blood pressure, chest pain, hardening of the arteries, etc., circulatory disorders and respiratory illnesses.

Out of 246 kinds of Chinese herb, Hawthorn Fruit is found mostly in the list of many formulas.

The herb may contain certain chemical constituents effectively in treatments of Nonalcoholic fatty liver disease (NAFLD).

3. Phytochemical Berberine and 4. Resveratrol

Berberine and resveratrol, the phytochemical found abundantly in many vegetables and fruits as well herbs and herbal formulae such as Polygonum hypoleucum Ohwi, and Artemisia sacrorum Ledeb., and formulae including Yinchenhao Decoction (, YCHD), Qushi Huayu Decoction (, QSHYD), and Danning Tablet, were found not only to improve biochemical and histological change in nonalcoholic fatty liver disease, but also associated in inhibiting lipid accumulation through adenosine monophosphate-activated protein kinase activation or up regulating low-density lipoprotein receptor (LDLR) expression, alleviating lipid peroxidation, and reducing the production of inflammatory cytokines.

In such instance, Berberine and resveratrol, may be considered as a potential treatment for nonalcoholic fatty liver disease in the future.

5. Phytochemical Triterpenoid 

Triterpenoid is a various unsaturated hydrocarbons, found in essential oils and oleoresins of plants, including Ilex hainanensis Merr.

In the study to test the effect of Triterpenoid-rich fraction (TP) from Ilex hainanensis Merr. on NAFLD with Male Sprague-Dawley (SD) rats fed a normal diet (control) or high fat diet (NAFLD model), after 4 weeks, the high fat diet group was orally administrated TF (250 mg/kg) for another two weeks.

TP not only improves the symptoms of the subjects, but also decreases the levels of triglyceride , total cholesterol, low-density lipoprotein cholesterol, abnormality of lipid accumulation , levels of inflammation and infection and apoptosis response in the liver. 

Of these results, TF is found to be effective in protecting liver against NAFLD by regulating lipids metabolism and alleviating insulin resistance, inflammation and oxidative stress.

6. Peony

Mu Dan Pi or Dan Pi (Cortex Moutan Radicis) is also known as peony. The acrid, bitter and mild cool herb has been used in TCM as anti micro organism, anti inflammatory agent and to enhance circulation and immune system, etc., as it clears heat and cools the blood, clears fire of yin deficiency, clear blood stasis and rid of clots, etc., by enhancing the functions of heart, liver and kidney channels.

Peony, a very popular Chinese herb is emerging as in many study for its Anti-inflammatory, anticoagulative, Anti-microbial and cytokine modulating effects, as well as properties as treatments of arthritis and asthma. 

In the study of the effects of peony in Non alcoholic liver disease caused by insulin resistance with Adult SD rats fed on high-fat-sugar-salt diet for 56 days, then divided randomly into nonalcoholic fatty liver model group, metformin group (0.2 g x kg(-1)) and total glucosides of peony group. 

Oral administration of total glucosides of paeony group, hyperinsulinaemia and insulin resistence were resisted, the levels of free fatty acids (FFA), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C)] were decreased, HDL-C were increased, the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), cholinesterase (ChE) were decreased and superoxide dismutase (SOD) were increased. The contents of malondialdehyde (MDA) were decreased. 

Of these result, researchers suggested that paeony may consist a potential effect in protecting liver function and modulate serum lipid for the fatty liver rats caused by insulin resistance.

7. Bay berry 

Bay berry is a species of Myrica gale, genus Myrica, belonging to the family Myricaceae. Beside many nutrients, it also consists chemical constituents of Gallic acid, quercetin hexoside, quercetin deoxyhexoside, quercetin, anthocyanins, flavonols, and elllagitannins, etc.

In a randomized, placebo-controlled, double-blind, crossover study of 44 participants (ages 18-25 y) given 250 mL of either bayberry juice or placebo twice daily for 4 wk, bay berry juice is found to decrease inflammation and infection, liver cell apoptosis, and death of liver tissues as well as reduction of the risk of steatosis progreeion to cause NALFD. 

Of that results, researchers suggested that consumption of bayberry juice for a period of 4 wk can protect against NAFLD and its juice may be a candidate for potential prevention and treatment of Non acoholic fatty liver disease(NALFD).

8. Green Tea

According to the University of Connecticut, Storrs, the efficacy of green tea for treatment of obese patients with nonalcoholic fatty liver disease is associated to polyphenolic catechins in induction of hypolipidemic, thermogenic, antioxidant, and anti-inflammatory activities.

These chemical compound have also found to mitigate the occurrence and progression of NAFLD.

Dr. Masterjohn C(7), the lead author said, “(The phytochemical compounds are) demonstrating the hepatoprotective properties of green tea and its catechins and the proposed mechanisms by which these targeted dietary agents protect against NAFLD”.

In mice fed on a high-fat diet for 24 weeks, then injected with EGCG (10, 20 and 40 mg·kg(-1)·d(-1), ip), for 4 weeks, researchers found that treated mice showed a significant improvement of high-fat diet in induced the body weight, grade 2 or 3 liver fatty degeneration (steatosis, lobular inflammation and ballooning), severe hyperlipidemia, hyperglycemia, hyperinsulinemia and insulin resistance..

The phytocheimcal EGCG, in dose-dependent also enhanced insulin clearance and upregulated IDE protein expression and enzyme activity(8) in regulated levels of glucose in the liver of treated mice.

In fact EGCG not only promoted weigh loss but also attenuated symptoms of mice with nonalcoholic fatty liver disease.

Administration of green tea polyphenols (GTP) on non-alcoholic fatty liver disease (NAFLD) in Zucker fatty (ZF) rats, not only decreased weight gain and significantly lowered visceral fat but also reduced fasting serum insulin, glucose and lipids levels(9), through ameliorated expression of hepatic TG accumulation and cytoplasmic lipid droplet(9) as well as diminished hepatic lipogenesis and triglycerides out flux from liver.

9. Anise

According to statistic, nonalcoholic fatty liver disease is one of most common cause of liver disease with a prevalence rate of 20%–30% in Western world.

In the comparison the effect of anise fruit essential oil and extract and risk of nonalcoholic fatty liver disease, researchers at the Islamic Azad University conducted a experiment of 60 rats randomly divided into ten groups, six in each group with NAFLD induced by using choline-deficient diet for 90 days and followed by 30 days of treatment with 25, 50, 100, and 200 mg/kg/day of hydroethanolic extract (AE) as well as 0.125, 0.25, and 0.5 mg/kg/day of essential oil (AO) and found that both applications exerted a significantly reverse activities in increased AE and AO plasma levels of total cholesterol, low-density lipoprotein, and triacylglycerol and decrease in high-density lipoprotein level caused by choline-deficient diet in dose-dependent manner.
Additional differentiation also found that AE and AO reduced the elevated levels of enzymes aspartate transaminase (AST) and alanine transaminase (ALT) which are considered as an indication of either liver injure or damage caused by the acute inflammation in the experiential subject model.

Observation of injection anise AE and AO also exerted a powerful antioxidant activity in significant lower over expression of ROS in exhibited free radical chain reaction in induction of oxidative stress to precipitated liver toxicity.
According to the histological findings, researchers concluded that both AE and AO display a substaintial effect in reduced macrovesicular steatohepatitis which is the leading cause of liver cancer.

Further analysis also addressed that both anise AE and AO demonstrated a strong effect in ameliorated lipid peroxidation induced by oxidative stress indicated by elevation of plasma level of 8-isoprostane which is correlated to the prevalence of non-alcoholic fatty liver disease (NAFLD).

Elevated 8-Isoprostane values activated by lipid peroxidation induced by injection of choline-deficient diet are also considered as a biomaker in patient with non alcoholic liver disease and correlated to with body mass index and with total cholesterol in NAFLD but did not significantly related to sex, age, biochemical data or iron metabolism markers in all liver diseases.

Therefore, people with high body mass index and high levels of total cholesterol levels are susceptible to increase risk of the diseases.
