Phytopharmacology of Tulsi- Basil
(Ocimum tenuiflorum, Ocimum sanctum) Part 1
(Ocimum tenuiflorum, Ocimum sanctum) Part 1
Introduction
There are many varieties of Basil. Their
phytochemistry, properties, culinary uses, medicinal uses etc. are more or less
similar. To avoid repetition and confusion I shall describe here Holi Basil AKA
Sweet Basil AKA Krishna Tulsi (Shyama Tulsi) AKA Saint Joseph’s Wort.
On account of its virtues viz. having many medicinal properties and
their applications, insect repellant property, ability to disinfect the
ambience and revivify malarious air; Hindus
regard Holy Basil as a sacred shrub. As the protecting spirit of the family, it
became inseparable from Hindu houses in India. They grow the herb in decorated
containers on the windowsills, on the balconies, in the courtyards and on the
patios.
Since childhood they chant ditties,
verses, hymns in admiration of the herb.

Tulsi in History
Prof. Shrinivas Tilak, who taught Religion
at Concordia University, Montreal has made this historical citation: In a
letter written to The Times, London, dated May 2, 1903 Dr. George
Birdwood, Professor of Anatomy, Grant Medical College, Bombay (now known as
Mumbai) said, "When the Victoria Gardens (now known as Jijaamaataa
Udyaana) were established in Bombay (now known as Mumbai), the men employed on
those works were pestered by mosquitoes. At the recommendation of the Hindu
managers, the whole boundary of the gardens was planted with holy Basil, on
which the plague of mosquitoes was at once abated, and fever altogether
disappeared from among the resident gardeners."

Tulsi: The Holi Basil
The name ‘Tulsi’ connotes “the incomparable one”.
Tulsi is a venerated plant in Hinduism. Since Tulsi has pleiotropic
pharmacological pharmacological activity, multifold chemical properties and
actions and botanical importance Hindus worship Tulsi. Of the many varieties,
Krishnaa or Shyaamaa Tulsi is selected for worship. Light or Rama Tulsi
possesses lesser medicinal value. Hence it does not attain high veneration as
Krishnaa or Shyaamaa Tulsi.
3. Tulsi as
A Deity
The presence of Tulsi plant symbolizes the religious
bent of a Hindu family. A Hindu household is considered ‘incomplete’ if it does
not have a Tulsi plant in the courtyard.
Tulsi-vrindavana
Many families have the Tulsi plant planted in a
specially built four sided structure having images of deities installed on all
four sides (Tulsi-vrindavana) and an
alcove (Konaadaa in Marathi) for a
small earthen oil lamp. Some households can even have up to a dozen Tulsi
plants on the verandah forming a “Tulsi-vana”- a miniature Tulsi forest.
4. The Holy
Herb
According to the “Gandharva Tantra” grounds overgrown
with Tulsi plants inspire concentration. Such places are considered ideal for
worship. The “Tulsi Manas Mandir at Varanasi is one such temple, where Tulsi is
worshiped along with other Hindu gods and goddesses. Believers of Lord Vishnu
(Vaishnavaites) worship the Tulsi leaf, because it pleases Lord Vishnu the
most. They also wear beaded necklaces made of Tulsi stems. Manufacture of these
Tulsi necklaces is a cottage industry in pilgrimages and temple towns.
5. Tulsi as
An Elixir
In English Tulsi is known by the name Holi Basil. The
juice of its leaves is used for treating inflammations, headaches, respiratory
ailments, stomach disorders and many other illnesses. It is considered to be an
adaptogen. The aroma of Holi Basil leaves is agreeable, so some people like to
add Holi Basil leaves to their tea to get a unique flavor.
Apart from its religious significance, Tulsi is of
great medicinal significance. Tulsi is a prime herb in Ayurvedic treatment. As
Tulsi is said to promote longevity Tulsi is regarded as a kind of “the elixir
of life”. Essential oil extracted from “Karpoora Tulsi” is mostly used for
medicinal purposes
As per the Christian tradition, it is believed that
Tulsi grew around Calvary, the place where Jesus was crucified. In Greece and
Rome Tulsi is valued for its medicinal use.
In Europe, folks place Tulsi (Basil) in the hands of
dead to ensure a safe journey to heaven. Egyptians and ancient Greeks believed
that placing Tulsi in the hands of the dead would open the gates of heaven for
a person passing on. [1]
Sanskrit meaning of Tulsi is the “incomparable one”.
It is also known as the queen of herbs. The name Basil is derived from the Greek word basileus meaning "king",
as it is believed to have grown above the spot where St. Constantine and Helen discovered the Holy Cross. The Oxford English Dictionary quotes speculations that basil may have
been used in "some royal unguent, bath, or medicine". An alternative
but rather unlikely etymology has "Basil" coming from the Latin
word basilicus, meaning dragon,
a fabulous creature that could kill with a look and being the root for basilisk. But this likely was a linguistic corruption of the Greek word. The theory may be based on a quaint superstition
that scorpions do much rest under these containers wherein Basil is planted.
Also it was believed that if a sprig of Basil were left under a container it
would in time turn to a scorpion. Superstition went so far that Hilarius, a
French physician, affirms that even smelling the plant might
breed a scorpion into the brain.
Basil has acquired a long
list of superstitions and lores associated with it. According to Culpepper if Holy Basil be
applied to venomous bites, 'draws the poison to it'. Mizaldus stated that if
sweet Basil be placed on a dung heap it would breed 'venomous beasts'. Pliny
recommended smelling it in vinegar for fainting. To the French it is 'herbe
royale'. In Malaysia and Iran it is planted on graves. In Egypt women would
scatter the Basil flowers on graves. The ancient Egyptians burned a mix of
basil and myrrh during religious rituals and used it in embalming the dead. To
the ancient Greeks, the Basil represented hate and misfortune. It was also
believed the plant would not grow unless subjected to verbal abuse at the time
of sowing. To the Romans it symbolized love. In parts of Italy Basil is still
considered a token of love. Traditionally, a woman would put a pot of Basil on
the balcony outside her room when she was ready to receive her suitor. In
Moldavia tradition holds that a lad will love any maiden from whom he accepts a
sprig (Marathi=Dahaalee) of Basil. In Haiti it is associated with Erzulie, the
Haitian goddess of love. The Haitians think Basil stimulates sensuality. Store
owners there would sprinkle Basil water over their places of business to drive
away evil spirits, thus opening the way for buyers [2]

Vaijayanti
tulas (Ocimum gratissium) is a
variable polymorphic complex species, often subdivided into subspecies,
varieties and forms, mainly based on differences in chemical content, the
morphology of the fruiting calyx, and on different degrees hairiness. Sometimes
Ocimum gratissium containing
chromosome counts: 2n=40, 48, 64; Ocimum suave
containing chromosomal counts: 2n=32, 48, 64 and Ocimum viride containing chromosome counts: 2n= 40, 48, 64 are
treated as one complex species Ocimum
gratissium. In fact they are three different species. Cross between Ocimum gratissium and Ocimum viride resulted in partially fertile F1 hybrides.

the state Maharashtra.

each of the two opposite axils of the leaves. The flowers are sessile and
appear as a cluster around the node), arranged in a terminal, simple or
branched raceme, 5 to 30 cm long; rachis lax, softly pubescent; bract sessile,

Geographical Distribution
Basil is a tender low-growing herb originally native
to India, Africa, Iran and other tropical regions of Asia having been
cultivated there for more than 5,000 years.
Basil is very sensitive to cold, with best growth in
hot, dry conditions. While most common varieties are treated as annuals some are perennial. Sweet Basil grows to about two to three in height while
Bush Basil grows to one foot in height.
Although Basils will grow best outdoors in bright
sunlight, they can be grown indoors in a pot and, like most herbs, in dappled
shade. They should be kept away from extremely cold drafts. They grow in a
light to sandy, well-drained nutrient rich soil having lots of humus and
minerals. The Basil can tolerate pH ranges starting from 4.3 to 8.4. When planted next to tomato plants, it wards
of the white fly, which plagues the tomatoes.
Several other Basils are grown in many regions of
China, Mediterranean, Indonesia, Northern Europe, northern states of the U.S.
and South Island of New Zealand. [27], [28], [29]
