INTRODUCTION
Ayurvedic medicine is a system of healing that originated
in ancient India.
In sanskrit
Ayur – Life or Living
Veda – Knowledge
So, Ayurveda has been defined as the “Knowledge of
living” or the “Science of longevity”.
4
Ayurveda is the science of health and healing practised by
ancient aryans which is based on the Atharvaveda, one of the
oldest scriptures of Hindus, about 3000 years old.
The object of ayurveda is to counteract the imbalance of three
essential elements, vata, pitta, kapha(air,bile and phlegm
respectively),which constitute the Tridosha from which the
body originates.
According to Drugs and Cosmetic Act 1940,ayurvedic
medicine includes all medicines intended for internal or
external use, for or in the diagnosis, treatment, mitigation or
prevention of disease or disorder in human beings or animals.
5
According to hypothesis of Ayurveda, the entire universe is
composed of five basic elements called PANCHAMAHABHUTA
and include space, air, energy ,liquid, and solid.
The variable combinations of these principles make tridosha in
human body.
These combinations are vata, pitta and kapha.
They have been interpreted in the following way.
Vata is composed of space and air. It is concerned with the
physical and mental activities which are activating or dynamic in
nature.
6
Vata represents nervous system,or nadichakra as per ayurvedic
terminology.
Pitta is composed of liquid and energy, and indicates
biochemical or energy systems.
Kapha is composed of solid and liquid and indicates various
tissues and organs.
Ayurvedic therapeutics is based on five pharmacological
principles (panchsheel) of the drug.
Those are as follows:
1.Rasa 2.Guna 3.Vipaka 4.Virya 5.Prabhava.
7
AYURVEDIC FORMULATIONS:
Different solvents (menstrum) used in preparations of
Ayurvedic formulations are water ,oils ,milk ,ghee ,cow’s
urine ,etc.
The use of sweetening agents ,binding agents, colorants,
flavouring principles, and other adjuvents is also very
common in ayurvedic preparations.
With an objective of obtaining maximum therapeutic benefit
and making the formulation palatable, different
pharmaceutical process are prescribed in ayurveda.

ANALYSIS OF AYURVEDIC DRUGS:
Several Ayurvedic medicines readily available are found
to contain steroids and heavy metals ,both are harmful to
the human body if taken in excess.
Ayurvedic medicines given by the vaidyas –be it in the
form of bhasma or churna which people swallow in with
great faith,could contain steroid and toxic metals such as
lead,mercury and arsenic.
10
In order to ensure quality control,quality assurance and safety
for ayurveda and siddha drugs, the quality of herbal products
need to be monitored with creation of awareness amongst all
concerned i.e.;
Physical analysis
Chemical analysis
Microbial analysis

AVALEHA Avaleha or Lehya is a semisolid preparation of drugs,
prepared with addition of jaggery,sugar or sugar-candy and
boiled with prescribed juices or decoction.
These preparations generally have
1) Kasaya or other liquids
2) Jaggery ,sugar or sugar-candy
3) Powders or pulps of certain drugs
4) Ghee or oil
5) Honey
51
Jaggery, sugar or sugar-candy is dissolved in the liquid and
strained to remove the foreign particles.
This solution is boiled over a moderate fire.
When pressed between two fingers if paka becomes
thready, or when it sinks in water without getting easily
dissolved, it should be removed from the fire.
Fine powders of drugs are then added in small quantities
and stirred continuosly to form a homogeneous mixture.
52
Ghee or oil, if mentioned, is added while the preparation is
still hot and mixed well.
Honey, if mentioned is added when the preparation becomes
cool and mixed well.
The Lehya should neither be hard nor a thick fluid .
When pulp of the drugs is added and ghee (or) oil is present in
the preparation, this can be rolled between the fingers.
When metals are mentioned, the bhasmas of the metals are
used.
In case of drugs like Bhallataka,purification process is to be
followed.
53
The lehya should be kept in glass or porcelain jars.
It can also be kept in a metal container which does not react
with it .
Normally Lehyas should be used within one year.
Eg. Kalyanavaleha, Draksavaleha, vasavaleha, bilvadileha and
surnavaleha.
