INTRODUCTION
Nature acts as one of the outstanding source of herbal medicine. Nature has provided a full as well as a complete package for various remedies to
cure all ailments of man and his life. Major portion of our population depends upon these herbal medicines. Either as a part of plant or as entire
plant or as a whole growing plant, these herbal medicines are turning to give a lot of important medicinal uses with fewer side effects.
Traditional use of these medicinal plant acts as a way to learn more about potential features of herbal medicines. Herbal plants have provided a
good source or huge variety of essential components like phenolic compounds, nitrogen compounds, vitamins, terpenoids and some other
secondary metabolites, which are rich in antioxidant, anti-inflammatory, antitumor, antibacterial, antiviral and various other activities. Herbal
plants have now become the target of chemists, biochemists and pharmacists. The research of these play a vital role for discovering and
developing new drugs which are medicinal in nature that hopefully have lesser side effects but show more effectiveness. Medicinal plants also
have non-medicinal uses such as flavors, foods and ornamentals species etc, [1,2].
The World Health Organization (WHO) assumed that 4 billion people, 80 percent of population use medicinal drug for various health issues.
Many pharmaceutical companies now a days working on these plants which are being collected either from rain forest or from other places rich
in medicinal herbs. There are number of plants derived pharmaceuticals medicines which are highly used in modern medicines with their
traditional uses. These medicinal plants are timely used by many people for curing various types of ailments [3-6].
There are many different types of systems of medicines in India like Ayurveda, Siddha, Unani and various local health traditions, use various
number of plants for the treatment of various diseases of mankind [7-10]. A lot of plants are used in treating various disease conditions they may
be in the form of tonics, anti-malarial, antipyretics, aphrodisiacs, expectorants, hepato-protective, anti-rheumatics, diuretics etc. A modern trend
has been observed in the research of these medicinal plants. Export import report suggests that the trade of plant and plant derived products in
the global market is around US $60 billion. As it is well known that India, with its rich-biodiversity and rich traditional systems provides a
strong base for a large number of plants which can be utilized in health care and common health problems of people. In present time allopathic
medicines showing lot of side effects which are very severe so it is very important to find out some herbal medicines for treating diseases.
Cedrus deodara is an evergreen tree (conifer) with an height of 85 m, almost rough black, bark and spreading branches, shoots with dimorphic
leaves 2-8 cm needle like with sharp pointed, flowers are monoecious, but some branches Bear flowers with one sex. All the parts of the flower
are bitter, pungent, in nature. Cedrus is a genus of Pinacea with tropical as well as subtropical distribution. The genus is mainly comprised of
trees which are cultivated may be for their usefulness for their ornamental purposes. Seeds usually shed in winter season. Deodara trees live up
to 600 years. Flowers come in September to October. Drained soil is well for the growth of these trees. High moisture is favorable for the growth
of the plant. Cold wind and frosts may cause injury to young treesM [11].

All parts of plant useful in curing diseases like inflammation, insomnia, cough, fever, urinary discharges, itching, tuberculosis, ophthalmic
disorders, disorders of mind, diseases of the skin and of the blood. The leaves of these plant help in reducing inflammation. The wood act as
expectorant and useful in curing piles, epilepsy, stones in the kidney and bladder, useful in fevers and in many other disorders. The oil is
antiseptic in nature and helpful in curing skin diseases, wounds, urogenital diseases, diaphoretic as well as insecticide. It may also cure fungal
diseases and act as sedative and cardio tonic too (Table 1) [14].
Chemical constituents
Cedrus deodara has been studied by lot of researcher and they concluded that there are lot of essential constituents of high range of structure are
seen in Figure 2. The chemicals in wood are wikstromal, matairesinol, dibenzylbutyrolactol,1,4-diaryl butane, benzofuranoid neo lingam [15],
cedrin (6-methyldihydromyricetin), taxifolin, cedeodarin (6-methyltaxifolin), dihydromyricetin, cedrinoside [16], deodardione, diosphenol,
limonenecarboxylic acid [17], ()-matairesinol, ()-nortrachelogenin, and a dibenzylbutyrolactollignan (4,4',9-trihydroxy-3,3'-dimethoxy-9,9'-
epoxylignan) [18]. A new dihydroflavonol named deodarin(3,4,5,6-tetrahydroxy-8-methyl dihydroflavonol) has been isolated from the stem bark
[19]. The extract of C. deodara needle (Ethanolic extract) showed the presence of lot of compounds viz. 10-nonacosanol, dibutyl phthalate,
protocatechuic acid, phthalic acid bis-(2-ethylhexyl) ester, (E)-1-O-p-coumaroylbeta-D-glucopyranoside and 5-p-trans-coumaroylguinic acid, 9-
hydroxy-dodecanoic acid, ethyl laurate, ethyl stearate, 3-betahydroxy-oleanolic acid methyl ester, beta-sitosterol, shikimic acid, methylconiferin
and ferulic acid beta-glucoside [20,21]. The essential oil of wood contain a sesquiterpenes-L II: Isohemacholone and sesquiterpenes L III:
deodarone, atlantone [22], α-himacholone, β himacholone [23,24], ά-pinene, β-pinene, myrcene [25], himachalene, cis-atlantone, ά-atlantone
[26].

Pharmacological activity
Many pharmacological activities of C. deodara have been reported in vivo and in vitro. Various parts of this plant bear anti-inflammatory,
immuno modulatory, antispasmodic, anticancer, antiapoptotic, antibacterial as well as other activities.
Anti-inflammatory activity
The oil extract of wood was used for its oral anti-inflammatory activity. The extract showed significant result in induced rat paw edema process
[17]. The oil extract (Volatile) was also studied for its anti-inflammatory activity by the process of induced arthritis. The extract showed
significant result here too [27,28].
Analgesic activity
The oil of wood of C. deodara was studied for its analgesic potential by acetic acid induced writhing response and hot plate reaction time model
in mice. Aspirin and morphine were used as reference control for study. Wood oil of C. deodara showed significant analgesic activity in both
levels of study [29].
Immunomodulatory activity
Models like neutrophil adhesion test in rats were used for studying volatile oil of wood of C. deodara in immunomodulatory activity [30].
Reaction of Athrus reaction in mice [31], SRBC-induced delay type hypersentivity (DTH) in mice [32,33] and oxazolone-induced contact
hypersensitivity in mice [34].
C. deodara oil of wood helps in inhibiting the adhesion of neutrophils to nylon fibers which are responsible for the simulation of blood vessels in
the cells (margination). This shows that the C. deodara wood oil lessens the amount of neutrophils in turn decreasing phagocytosis action and
also the release of various enzymes that make inflammation even more worsen [33].
C. deodara wood oil significantly shows the inhibition for Arthrus reaction due to inhibitory effect characterized in the following reaction:
Formation of precipitation of an immune complex at the site of injection, Activation of compliment system, neutrophil aggregation, release of
lysosomal enzymes etc [35]. In the early event hypersensitivity reaction to oxazolone, mast cell degranulation has been reported [36]. It is due to
mast cell stabilization. This proved that C. deodara oil manly of wood produces and inhibitory effects on humoral as well as cell-mediated
immune responses and hence shows lot of usefulness in curing inflammatory diseases.
Antispasmodic activity
Himachalol is one of the chief constituent of wood of C. deodara, which likely to have antispasmodic activity. The pharmacological studies of
himachalol on different isolated smooth muscles (Rat uterus, pig ileum and rabbit jejunum) and against various other agonist’s histamine,
serotonin, nicotine, acetylcholine etc., proved spasmolytic activity. This antagonist activity had no relaxing effect when given alone. Himachalol
had much faster and better action as compare to papaverine which compared to Himachalol. Intravenous injection of Himachalol when given to
cat produces a dose dependent fall in blood pressure and also causes an increased femoral blood flow [24].
Antioxidant activity
Brain and nervous system are mainly the two parts of our body which are highly prone to free radical damage as our nervous system and brain
are rich in lipid and iron. C. deodara was known and also evaluated to have high antioxidant property [37]. Fractionation and purification are the
two processes which are involved in the identification of antioxidant components mainly from dried heart wood powder of C. deodara.
Anti-malarial activity
Oil from the C. deodara was studied for bioactivity against the adults of Culexquinue fasciatus and Aedesaegypti. Various Wood chips of C.
deodara were used to get essential oils which are useful in antimalarial activity. There is an apparatus use to crush wood chips to get essential
oils is Clevenger’s. Adults of Aedes aegypti were mostly insensitive to essential oil of C. deodara. Plants showed moderate activity [26].
Antiallergic activity
Various phytochemical investigations proved that various medicinal as well as essential constituents of the plant are responsible for curing
different diseases e.g. Himachalol is one of the best constituent with anti-allergic property [38].
Insecticidal activity
Himalayan cedar wood oil fractions and chromatograph were bio assayed against the pulse beetle (Calloso bruchusanalis F.) and the housefly
(Musca domestica L.). All fractions showed insecticidal activity. Evaluation of fractions I and V and β-himachalene (naturally occurring)
sesquiterpenes indicated mortality against the pulse bettle. These natural products of plant serve suitable for the development of commercial
insecticides [39].
Antihyperglycemic activity
The ethanolic extract of wood of C. deodara possesses antihyperglycemic activity mainly on streptozotocin-induced diabetic rats from 1 to 7 h.
Lowering of blood pressure was found at 7 h treatment [40]. Plant shows 6% fall in blood glucose profile in single dose experiment on
streptozotocin-induced diabetic rats [41-43]. Antihyperglycemic preparation was also obtained and evaluated from the ethanolic extract of
Cedrus deodara [44].
Antisarcoptic mange activity
C. deodara proved to contain two commonly acaricidal drugs that are OCD and Benzyl Benzoate (BB), respectively, which are used to cure
infection of Sarcoptesmites. These drugs are applied on effected part in alternative days and recoveries in skin lesions were observed. Blood
samples were also collected and analyzed after every 10 days of Post Treatment (PT). C. deodara oil was more effective in controlling sarcoptic
mange in sheep [45].
Anticonvulsant activity
Alcoholic extract of heart wood of plant C. deodara was studied for its highly anticonvulsant activity by Pentylenetetrazole (PTZ) induced and

Maximal Electro Shock (MES) induced in mice. The alcoholic extract showed increase in the onset of tonic seizures in PTZ and also decrease in
the time of tonic extensor phase in MES. Modulation of GABA level were estimated when administered in rat brain and showed significant
result. This proves that alcoholic extract of C. deodara have significant anticonvulsant activity through GABA levels in brain [46,47].
DISCUSSION AND CONCLUSION
Herbal medicines are considered as a rich source of medicines which can be used in drug development and synthesis. These herbal medicines
play an important role in the development of human culture around the whole world. Herbal medicines have been proved better and even best
against allopathic medicines. From the present review it is clear that C. deodara have many qualities and features including anti-inflammatory,
antitumor, anti-bacterial, antifungal and various other and possesses great influence on nervous system. Various studies can be conducted in
multiple animal based models for understanding their mechanism of action.

The present study was performed to evaluate the hypoglycemic and antioxidant effect of aqueous extract of Aegle marmelos leaves (AML) on diabetic rats. Male albino rats were randomly divided into three groups: Group I: Control; Group II: Diabetic rats; and Group III: Diabetic rats administered AML. Glucose, urea and glutathione-S-transferase (GST) in plasma, glutathione (GSH) and malondialdehyde (MDA) levels in erythrocytes were estimated in all the groups at the end of four weeks. There was a decrease in blood glucose at the end of four weeks in group III animals compared with group II, however it did not reach the control levels. There was an increase in erythrocyte GSH and a decrease in MDA in group III as compared to group II. The plasma GST levels were raised in diabetic rats when compared to controls. In the group III animals, there was a decrease in GST as compared to group II. Owing to hypoglycemic and antioxidant properties, AML may be useful in the long-term management of diabetes.

Two commonly used acaricidal drugs in India containing oil Cedrus deodara (OCD) and benzyl benzoate (BB), respectively, were used in 24 lambs (3–6 months) naturally infected with Sarcoptes mites. The lambs were divided in three equal groups. Two groups were kept as treated groups and a third as control. Drugs were applied locally on affected parts on alternate days and recovery changes in skin lesions were observed regularly at the time of application. Blood samples from each group were collected and analysed for total erythrocytes, leukocytes, and haemoglobin concentration every 10 d Post treatment (PT). The two treated groups responded to the treatment but recovery in the C. deodara group (CDG) was faster and lesions were free from mites after 5 applications (tenth day) as compared to the seventh application (fourteenth day) in the benzyl benzoate group (BBG). Erythrocyte and leukocyte counts were significantly different in treated groups as compared to control. Animals treated with OCD had significantly more erythrocyte and leukocyte counts compared to control; however, haemoglobin did not show significant difference. Oil of C. deodara was found more efficacious in controlling sarcoptic mange in sheep.

The ethanolic extract of Annona squamosa L. (Annonaceae) leaves was administered orally at different doses to normal as well as streptozotocin (STZ)-induced diabetic rats and alloxan-induced diabetic rabbits. The dose of 350 mg/kg body weight (bw) reduced the fasting blood glucose (FBG) level by 6.0% within 1 h, whereas, the peak blood glucose at 1 h during glucose tolerance test (GTT) was reduced by 17.1% in normal rats. The same dose of ethanolic extract reduced FBG by 26.8% and improved glucose tolerance by 38.5 and 40.6% at 1 and 2 h, respectively, during GTT in alloxan-induced diabetic rabbits. In STZ-diabetic rats, a fall of 13.0% in FBG and an improvement in glucose tolerance by 37.2 and 60.6% at 1 and 2 h, respectively, was observed during GTT. The dose of 350 mg/kg bw of ethanolic extract in 10-day treatment of a group of STZ-diabetic rats produced 73.3% fall in FBG level and no sugar was observed in fasting urine. Treatment of severely-diabetic rabbits for 15 days with a dose of 350 mg/kg of extract reduce FBG by 52.7% and urine sugar by 75%. It brought about fall in the level of total cholesterol (TC) by 49.3% with increase of 30.3% in high-density lipoprotein (HDL) and decrease of 71.9 and 28.7% in low-density lipoprotein (LDL) and triglycerides (TG) levels, respectively.
