AMLA
*SYNONYMS-Embica,indiangoose berry,Amalki.
*Taxonomical classification-
Kingdom : Plantae
Division : Angiospermae
Class : Dicotyledonae
Order : Geraniales
Family : Euphorbiaceae
Genus : Emblica
Species : officinalis Geartn.
*BIOLOGICAL SOURCE-This consist of dried as well as fresh fruit
3. of the plant Embelica officinali belonging to family Euphorbiaceae.
*GEOGRAPHICAL SOURCE- It is a small size tree found in forest of
India .it is also found in sri Lanka and myanmar.
* CULTIVATION -Amla can grow in light as well as the heavy soils.
It is grown under the tropical conditions. The
young plants are protected from the hot winds as
they dye easily. Amla is generally propagated
through seeds. It requires proper sunlight. It is
irrigated during the
monsoon season.
*-Soil and Climate-
Amla can be grown in light as well as heavy soils
except purely sandy soil. Calcareous soil with
rocky substratum can also be good. However,
well drained fertile loamy soil is the best for
higher yield. The plant have capacity for
adaptation to dry regions and can also grow in
moderately alkaline soils. It is grown extensively
under tropical condition. Annual rainfall of 630-
800 mm have given good yield. The young plants
up to the age of 3 years should be protected from
hot wind during May-June and from frost during
winter months. The mature plants can tolerate
freezing temperature as well as temperature up to
460 °C.
*- Planting-
Amla is generally propagated through seeds, but
seed propagated trees bear inferior quality fruits
and have a long gestation period. Shield budding
is done on one year old seedlings with buds
collected from superior strains yielding big size
fruits. Older trees of inferior types can be
rejuvenated and easily changed into superior type
by top working.
The pits of 1m3 are prepared during May-June at
a distance of 4.5 m spacing and should be left for
15-20 days exposed to sunlight. Each pit should
be filled with surface soil mixed with 15 kg farm
yard manure and one kg of super phosphate
before planting the grafted seedli.
*-Manures,fertilizers and pesticide-
The medicinal plants have to be grown without
chemical fertilizers and use of pesticides. Organic
4. manures like, Farm Yard Manure (FYM),
VermiCompost, Green Manure etc. may be used
as per requirement of the species. To prevent
diseases, bio-pesticides could be prepared (either
single or mixture) from Neem (kernel, seeds &
leaves), Chitrakmool, Datura, Cow's urine
etc. Biofertilizers such as Azotobacter,
phosphobacteria and Vesicular Arbuscular
Mycorrhiza (VAM) boost the plant growth.
*MORPHOLOGY-
colour - Green changing to light yellow or brick
red
When matured.
Odour- none
Taste- Sore and astringent .
Size - 1.5 to2.5 cm in diameter.
Shape- The fruits are depressed ,globose.
*MICROSCOPE-
Transverse section of fruits consisted of a thin,
continuous membranous layer of epidermis
comprising of less conspicuous cells smaller in size.
Inner epidermis was fairly wider made up of
hypodermal layer made up of parenchymatous cells
rectangular in shape followed by large compact cells.
The cells were variable in shape and size. The
parenchymatous region represented the mesocarp of
the fruit and the thin epidermal layer was the epicarp
(Fig. 1). The mesocarp was well vascularised. Small
vascular strands were wide spread in the mesocarp.
The vascular strands varied in size;
some were well developed with collateral xylem and
phloem .whereas others were smaller and
less distinct. Xylem consisted of narrow, thick walled
with lignified clusters. Phloem included a prominent
mass of sieve elements. Bundle sheath cells were not
evident. Sections stained with neutral red exhibited
some of the mesocarp cells being filled with reddish
amorphous substance, lipoidal in nature, distributed
randomly . Calcium oxalate crystals were clear
when viewed under polarised light interspersed
with mesocarp cells. Raphides observed in
5. parenchymatous cells consisted of numerous thin
pointed needles packed within the bundle. The
needles were loosely packed .

Pemminati has checked the antidepressant
activity of aqueous extract of fruits of E. officinalis in
inbred adult male Swiss Albino mice weighing 25-30g.
* Immune modulatory activity-
There was considerable dose dependent raise in
haemagglutination antibody titre, macrophage migration
index, hypersensitivity reaction, respiratory burst activity
of the peritoneal macrophages, total leukocyte count,
percentage lymphocyte distribution, serum globulin and
relative lymphoid organ weight in Emblica treated albino
mice indicating its ability to stimulate humoral and cell
mediated immunity along with macrophage phagocyte.

cordifolia, Trigonella foenum and Emblica officinalis.
*Cytotoxic effects-
To evaluate the immunostimulatory and side effects of
Triphala in a clinical phase I, all the volunteers took
Triphala for two weeks (3 capsules per day). As complete
physical examinations, routine laboratory analysis and
immunological studies were performed before ingestion
and after initial meeting for 4 consecutive weeks.
*Hypolipidemic activity-
Amla fruit have been reported to have significant anti-
hyperlipidemic, hypolipidemic, and anti-atherogenic
effect . Treatment with Emblica
officinalis caused significant reduction of Total Cholesterol
(TC), Low Density Lipoprotein (LDL), triglyceride (TG)
and Very Low Density Lipoprotein (VLDL), and a
significant increase in High Density Lipoprotein (HDL)
levels in patients with type II hyperlipidemia. Both
treatments from E. officinalis and simvastatin produced
significant reduction in blood pressure;
*USES-
*Treat cardiac disease-

of honey and 100 Gms of milk after lunch cures chronic piles
problem.ried amla seeds mixed with honey.
* TOXICITY-
Toxicity study: During acute toxicity study, E.
10. officinalis HAE administered @ 250, 500 and 1000
mg/kg, once orally to different groups of rats caused no
mortality up to 48 hr. Hence, the LD50 of E. officinalis is
more than 1000 mg/kg. The chronic toxicity of E.
officinalis HAE was determined in different groups of
rats according to the doses as given for acute toxicity
study. During 3 weeks, E. officinalis did not cause any
untoward effect. No gross observational effects were
observed at any of the doses of E. officinalis during acute
and chronic toxicity studies.
The acute and chronic toxicity studies with extract
provide a great information regarding the useful
properties likely to possessed by the extract and at the
same time provide the LD50. The development of signs
and symptoms during gross observational studies gives
an idea regarding the type of drug action, and the
therapeutic dose and route of administration of drug to be
used.
