Health benefits of Indian gooseberry (Emblica officinalis)
Emblica Officinalis is arguably the most important medicinal plant in the Indian traditional system of medicine, the Ayurveda .
The fruit also known as Indian gooseberry or Amla, has been an herbal component of Thai traditional recipes believed to slow down the aging process  but is also used to treat many ailments such as common cold and fever, as a diuretic, laxative, liver tonic, refrigerant, stomachic, restorative, alterative, antipyretic, anti-inflammatory, hair tonic, to prevent peptic ulcer and dyspepsia, and as a digestive .
It is also the source of Indian Gooseberry oil and Indian Gooseberry juice. Image: See credits under ref.  below.
Common name: Indian gooseberry, Amla, Emblic, Emblic myrobalan, Malacca tree
Preclinical studies have shown some Indian gooseberry benefits. Amla possesses:
- wound healing,
- nephroprotective, and
- neuroprotective properties .
In traditional Indian medicine Ayurveda, the use of Emblica Officinalis extends to all parts of the plant including the fruit, seed, leaves, root, bark and flowers are used in various herbal preparations for the treatment of diabetes mellitus, chronic diarrhoea, anti-inflammatory, antipyretic  antitumour, antioxidant and analgesic [7,8,9], but how many of those properties have been scientifically founded on facts? Let's see some of them.
EMBLICA OFFICINALIS FOR CARIES PREVENTION
Streptococcus mutants, a gram-positive oral bacterium, has been traditionally identified as the primary cause of dental caries.
In spite the use of traditional pharmaceutical remedies may help to prevent this dental disease, concerns over the toxicity of some of the chemicals used to treat it, namely the anti-plaque agent chlorhexidine, have raised the interests of scientists and researchers towards the search for other more natural sources of active constituents that may help to fight caries without any undesirable side effects.

One of the reasons why more and more scientists and researchers focus on active constituents provided by natural products as herbs and plants is the lack of toxicity and contraindications of most of them.
The standard antiplaque agent (cholorhexidine), which is being used in most of the dental care products, has several reports of being genotoxic [6,10].
On the contrary, the fruit of Emblica Officinalis (amla) is consumed raw which rules out every possibility of being toxic , something that proves how Emblica Officinalis fruit extracts could potentially be used as a source of active constituents for alternative and complementary medicine for the treatment and prevention of dental caries by inhibiting the virulence factors of Streptococcus mutans.
In another line of study, the use of Emblica Officinalis against the cariogenic effects of Streptococcus mutans, a causative micro-organism for cavities, showed how Emblica Officinalis fruit extracts could potentially be used as an alternative and complementary medicine for dental caries.
Dental caries is an irreversible localized infection that results in the progressive tooth decay [6,7]. Amla (Indian gooseberry) is also known to possess hypolipidemic properties .
EMBLICA OFFICINALIS AS RASAYANA
Rasayana is defined as any herb, food, or activity which confers youthfulness and cures diseases. If taken in a proper way, Rasayana prevents early ageing and keeps the person young and active, both physically and mentally .

At least, in one study performed using Drosophila, an organism commonly used to test Ayurvedic medicines, Emblica Officinalis showed to be able to enhance the sexual activity .
ANTI-NEOPLASTIC EFFECTS OF INDIAN GOOSEBERRY
The use of Indian gooseberry as anti-neoplastic (preventing, inhibiting or halting tumours) has also been documented in experimental studies, where it has been shown that Emblica Officinalis and some of its phytochemicals such as:
- gallic acid,
- ellagic acid,
- some norsesquiterpenoids,
- elaeocarpusin, and
- prodelphinidins B1 and B2
It also possesses antineoplastic effects . Others as its radio modulator, chemo modulatory, chemopreventive effects, free radical scavenging, antioxidant, anti-inflammatory, antimutagenic and immunomodulatory activities, have shown to be also properties that are efficacious in the treatment and prevention of cancer .
Gallic acid, a type of phenolic acid, is also found in other herbs as Witch hazel and is known to exert antifungal and anti-viral properties, also used as a remote astringent that compresses blood vessels in cases of internal haemorrhages .
TRIPHALA AND PANCREATIC CANCER
Triphala is another Ayurvedic herbal Rasayana (herb, food, or activity which confers youthfulness and cures diseases), composed of equal parts of the fruits Amalaki (Phyllanthus Emblica), Bibhitaki (Terminalia Billerica), and Haritaki (Terminalia chebula) [11,22].
In spite Triphala was already commonly used in Ayurvedic medicine to treat a wide range of ailments and diseases, its potential use against human pancreatic cancer has only been documented since 2008.
In 2008 scientists and researchers from the Texas Tech University of Health Sciences discovered that Triphala effective in inhibiting the growth of human pancreatic cancer cells in both cellular and in vivo model .
EMBLICA OFFICINALIS HYPOLIPIDEMIC PROPERTIES
Amla (Indian gooseberry) is also known to possess hypolipidemic properties . In a study performed in ovariectomized rats, Amla Amla (Indian gooseberry) is also known to possess hypolipidemic properties . In a study performed in ovariectomized rats, Amla decreased low-density lipoprotein cholesterol and increased HDL cholesterol .
HEPATOPROTECTIVE ACTIVITY OF EMBLICA OFFICINALIS
Some studies indicates the propensity of Emblica Officinalis extracts to improve antioxidant defences in HepG2 cells . The potential hepatoprotective activity of Emblica Officinalis is mainly attributed to the antioxidant potential exhibited by this herb .
In some cases the use of Emblica Officinalis as a hepatoprotective agent has been combined with quercetin, a type of flavonoid with very powerful antioxidant and anti-inflammatory properties found in many fruits, as apple, green and black tea, onions, leaves, vegetables and even grains .
