1. CLOVE
• Syn: Lavang
• Source: dried flower buds of
Syzygium aromaticum
(Eugenia caryophyllus),
• Family: Myrtaceae
• GS: Molucca or Clove
Islands, Zanzibar, Pemba,
Madagascar, Indonesia &
Brazil.
HISTORY OF CLOVE
Cloves were used in China as early
as 266 BC, and by the 4th
century, they were known in
Europe,
although
very
expensive.
Same as with nutmeg, the Dutch
also destroyed all trees from
surrounding native islands to
secure a monopoly, and
cultivated them only in a small
group of islands.
In 1770, the French managed to
introduce clove trees to
Mauritius,
and
started
cultivating them there, as well
as in Zanzibar, Penang and
Sumatra.
COLLECTION & PREPARATION
The flower buds are collected when the lower part turns greencrimson.
• In Zanzibar & Pemba collection takes place twice yearly, between
august and December.
• The inflorescence are collected from movable platforms.
• The cloves are dried in the Open air on mats & separated from their
Peduncles, the later forming a separate article of commerce
known as Clove stalks.
• If left on the tree for too long, the buds open & the petals fall, leaving
“brown cloves”.
• Later the fruits known as “mother cloves” are produced.
• A small portion of these, usually at a stage intermediate between that
of a clove and a fully ripe fruits, are frequently found in the drug.
• Cloves are imported in bales covered with matting made from string
of coconut leaves.
•
MACROSCOPICAL FEATURES
-Cloves are 10-17.5 mm long.
-Penang and Amboyna varieties
are the largest and plumpest.
-Zangibar variety is of good
quality and smaller and leaner
comparatively a blackish brown
rather than reddish brown color.
-The head consists of 4 slightly
projecting calyx teeth, 4
membranous petals and
numerous incurved stamens
around a large style.
-Odour: Spicy & Pungent
-Taste: Aromatic
MICROSCOPICAL FEATURES
Heavy cuticularized epidermis
Numerous oil cells (shizolysigenous)
Calcium oxalates (cluster crystals & prisms)

CLOVE OIL
Oil distilled in Europe and
the US normally does
not need purification,
while oil distilled in
other areas (e.g.
Madagascar) does.
After purification the oil
is sold with varying
eugenol contents.
Oil of cloves is yellow or
colourless, is slightly
heavier than water.
CLOVE OIL - CONSTITUENTS
• Volatile oils – mainly eugenol & acetyleugenol
• Sesquiterpenes (α and β caryophyllenes)
• Oil of clove – like other volatile/essential oils –
should be stored in a well-fitted, air-tight
container, & should be protected from light &
heat.

•
•
•

Mainly obtained from cultivated plants (propagated by seedlings or
vegetatively [problematic due to virus infection] ).
Capsules on the same raceme ripen at different times and it is important to
collect them when nearly ripe and before that split to shed their seeds. It is
best to cutt off each fruit at the correct stage with a pair of short-bladed
scissors.
In India & Srilanka, flowering and fruiting continues for practically whole year
but most crop is collected from October to December
Too rapied drying is avoided, as it causes fruits to split and shed their seeds.
Sometimes the capsules are re-moistened and further exposed to the sun-but
this sun bleaching though improving appearance, also increases the number
of split fruits.
Bleaching may also done by placing tray of fruits over burning sulphur.
Soaking fruits for 10min. In 2% Sod. Carbonate solution before drying.
Capsules have the remains of the calyx at the apex and stalk at the base,
removed either by hand clipping or by machines.
Fruits then graded by means of sieves into longs, mediums and shorts and
tiny.
If sulphur bleached, are aired in the open before being packed for export.
COLLECTION & PREPARATION
• Fruits are dried slowly
(outdoors or indoors).
• Too rapid drying – capsules split
& shed seeds
• Calyx at the apex of the stalk
and the stalk at the base may
be removed.
• Fruits are graded with a sift into
‘longs’, ‘mediums’, ‘shorts’ &
‘tiny’.
• If they have been sulphur –
bleached (improved colour), it
will be aired outdoors before
packed for transport.
MACROSCOPICAL FEATURES
• Plant is reed-like - > 4 m, with long leaves growing from
the rhizome.
• Fruits – capsular: inferior, ovoid, 1-2 cm long.
• Apex: shortly beaked & shows floral remains.
• Base: rounded & shows the remain of a stalk.
• Internally the capsule is 3-celled; each cell contains x2
row of seeds.
• Each seed: Slightly angular, 4mm long & 3 mm broad.
• Colour: dark red-brown (fully ripe seeds)  paler in
unripe seeds.
• Strong, pleasant, aromatic odour
• Pungent taste

1. ACONITE
• Syn: wolfbane root
• Source: dried roots of Aconitum napellus (Europe)
A. Japonicum (Japan), A. carmichaelli (China),
A.chasmanthum (India)
• Family: Ranunculaceae
• GS: Western Europe-spain, Himalaya
• Toxic principle: total alkaloid 0.3-1.2%
• terpene ester alkaloids: 30% aconitine,
mesoaconitine,hypaconitine, neopelline, napelline,
neoline
• Toxicity. All species of monkshood should be considered toxic to humans
and animals. All parts of the plant are toxic, especially the roots, seeds,
and new leaves. Horses have been fatally poisoned after consuming
0.075% of their body weight of the plant. The alkaloids can be absorbed
through the skin and may cause poisoning in humans handling the plant.
• Mechanism of toxicologic damage. Aconitine-type diterpene alkaloids
bind sodium channels, causing persistant activation.
• Diagnosis
• Clinical signs. Clinical signs are similar to those caused by larkspur
poisoning. Within a few hours of ingestion, restlessness, and excessive
salivation are seen. Animals develop muscle weakness and hypotension
and have difficulty breathing. Eventually, affected animals will collapse in
lateral recumbancy. Death may occur several hours to days postingestion due to either heart block and ventricular fibrillation or to
respiratory failure.
• Lesions. No lesions are seen.
• Treatment. No treatment has been proven effective in monkshood
poisoning. Affected animals should be stressed as little as possible.
Symptomatic treatment with intravenous fluids may be helpful. Vomiting
and diarrhea should be controlled. Oral activated charcoal and osmotic
laxatives may be helpful to reduce absorption of alkaloids from the GI
tract.
• Use: arrow poison,
potent-quick acting
poison
-not used internally in
UK except in
homeopathic doses
-formerly used for antineuralgic liniment
2. CURARE

COLLECTION & PREPARATION

The balsam is collected
from trees that are
around 10 years old in
the month of
November or
December i.e. by the
end of rainy season

The trunk is beaten at
an area of 30x15 cm
using the handle of the
axe or a stone or a
stick.

As peru balsam is a
pathological resin,
which is present only
in the young twigs, a
secretion of the
balsam takes place
after 5 days

A rag is placed under
the bark so that it can
absorb the resin

Balsam sinks at the
bottom of water, the
water is decanted,
balsam collected,
packed in tins and
exported

The rags, which are
collected, are put into
strong rope bags,
which are twisted at
the ends and pressed,
so that balsam falls
into boiling water

The resin flow for
about 5-6 weeks and
the fresh area on the
bark are beaten and
scorched.

Once the bark is
exhausted the bark is
removed and the
young wood is also
treated in similar
manner

  • 27. 1. CLOVE • Syn: Lavang • Source: dried flower buds of Syzygium aromaticum (Eugenia caryophyllus), • Family: Myrtaceae • GS: Molucca or Clove Islands, Zanzibar, Pemba, Madagascar, Indonesia & Brazil.
  • 28. HISTORY OF CLOVE Cloves were used in China as early as 266 BC, and by the 4th century, they were known in Europe, although very expensive. Same as with nutmeg, the Dutch also destroyed all trees from surrounding native islands to secure a monopoly, and cultivated them only in a small group of islands. In 1770, the French managed to introduce clove trees to Mauritius, and started cultivating them there, as well as in Zanzibar, Penang and Sumatra.
  • 29. COLLECTION & PREPARATION The flower buds are collected when the lower part turns greencrimson. • In Zanzibar & Pemba collection takes place twice yearly, between august and December. • The inflorescence are collected from movable platforms. • The cloves are dried in the Open air on mats & separated from their Peduncles, the later forming a separate article of commerce known as Clove stalks. • If left on the tree for too long, the buds open & the petals fall, leaving “brown cloves”. • Later the fruits known as “mother cloves” are produced. • A small portion of these, usually at a stage intermediate between that of a clove and a fully ripe fruits, are frequently found in the drug. • Cloves are imported in bales covered with matting made from string of coconut leaves. •
  • 30. MACROSCOPICAL FEATURES -Cloves are 10-17.5 mm long. -Penang and Amboyna varieties are the largest and plumpest. -Zangibar variety is of good quality and smaller and leaner comparatively a blackish brown rather than reddish brown color. -The head consists of 4 slightly projecting calyx teeth, 4 membranous petals and numerous incurved stamens around a large style. -Odour: Spicy & Pungent -Taste: Aromatic
  • 31. MICROSCOPICAL FEATURES Heavy cuticularized epidermis Numerous oil cells (shizolysigenous) Calcium oxalates (cluster crystals & prisms) Stomata (epidermis of sepals) Starch (Fruit – “mother cloves”) Lignified sclereids
  • 34. CONSTITUENTS • • • • • • • • • • • 14-21% Volatile oils 10-13% tannin Various triterpene and esters Glycosides of : aliphatic and monoterpenoid alcohol, eugenol, isoeugenol, farnesol, nerolidol, sitosterol, stigmasterol and campestrol
  • 36. USES OF CLOVE -Stimulant aromatic -as a Spice -For the preparation of volatile oil -Sesquiterpenes: potential anti-carcinogenic compounds
  • 37. CLOVE OIL Oil distilled in Europe and the US normally does not need purification, while oil distilled in other areas (e.g. Madagascar) does. After purification the oil is sold with varying eugenol contents. Oil of cloves is yellow or colourless, is slightly heavier than water.
  • 38. CLOVE OIL - CONSTITUENTS • Volatile oils – mainly eugenol & acetyleugenol • Sesquiterpenes (α and β caryophyllenes) • Oil of clove – like other volatile/essential oils – should be stored in a well-fitted, air-tight container, & should be protected from light & heat.
  • 39. CLOVE OIL - USES Anti-septic Aromatic Stimulant Flavouring Agent
  • 40. 2. CARDAMOM FRUIT & OIL Syn: Ilaychi Source: dried, nearly dried ripe fruits of Elettaria cardamomum Var. miniscula Family: Zingiberaceae PARTS USED: Seeds (should be kept in the fruit until ready to be used – Prevents loss of volatile oils). (3RD most expensive spice).
  • 41. Elettaria cardamomum • GEOGRAPHICAL SOURCES • Sri Lanka • Southern IndiaAlleppy • Guatemala • HISTORY • Traditional Indian ceremonies
  • 42. PRODUCTION, COLLECTION & PREPARATION • • • • • • • • • • Mainly obtained from cultivated plants (propagated by seedlings or vegetatively [problematic due to virus infection] ). Capsules on the same raceme ripen at different times and it is important to collect them when nearly ripe and before that split to shed their seeds. It is best to cutt off each fruit at the correct stage with a pair of short-bladed scissors. In India & Srilanka, flowering and fruiting continues for practically whole year but most crop is collected from October to December Too rapied drying is avoided, as it causes fruits to split and shed their seeds. Sometimes the capsules are re-moistened and further exposed to the sun-but this sun bleaching though improving appearance, also increases the number of split fruits. Bleaching may also done by placing tray of fruits over burning sulphur. Soaking fruits for 10min. In 2% Sod. Carbonate solution before drying. Capsules have the remains of the calyx at the apex and stalk at the base, removed either by hand clipping or by machines. Fruits then graded by means of sieves into longs, mediums and shorts and tiny. If sulphur bleached, are aired in the open before being packed for export.
  • 43. COLLECTION & PREPARATION • Fruits are dried slowly (outdoors or indoors). • Too rapid drying – capsules split & shed seeds • Calyx at the apex of the stalk and the stalk at the base may be removed. • Fruits are graded with a sift into ‘longs’, ‘mediums’, ‘shorts’ & ‘tiny’. • If they have been sulphur – bleached (improved colour), it will be aired outdoors before packed for transport.
  • 44. MACROSCOPICAL FEATURES • Plant is reed-like - > 4 m, with long leaves growing from the rhizome. • Fruits – capsular: inferior, ovoid, 1-2 cm long. • Apex: shortly beaked & shows floral remains. • Base: rounded & shows the remain of a stalk. • Internally the capsule is 3-celled; each cell contains x2 row of seeds. • Each seed: Slightly angular, 4mm long & 3 mm broad. • Colour: dark red-brown (fully ripe seeds)  paler in unripe seeds. • Strong, pleasant, aromatic odour • Pungent taste
  • 45. MICROSCOPICAL FEATURES • • • • Oil cells Predominant Parenchyma (yellow colour) Cells containing silica Starch grains
  • 49. VARIETIES & ADULTERANTS • ADULTERATION – Powdered drug adulterated with the fruit pericarp (powdered). • ALLIED HERBS – Official variety – E. cardamomum var miniscula – Other: E. cardamomum var major (more elongated & sometimes 4 cm long with dark brown pericarps) – Amomum aromaticum (Bengal cardamom) – Amomum subulatum (Nepal cardamom) – Amomum cardamomum (Java cardamom)
  • 50. CHEMICAL CONSTITUENTS 2.8 – 6.2 % volatile oil (BP-NLT 4%) Abundant starch (up to 50%) Fixed oil (1 – 10%) Calcium oxalate • OIL • Terpinyl acetate • Cineole • Monoterpenes (alcohol+ester) • • • • Cineol
  • 51. Elettaria: ACTIONS & USES • Flavouring agent (curries & biscuits) • Liqueur manufacture • Small amount is used for pharmaceutical manufacture (Compound Tincture of Cardamom).
  • 52. 3. Digitalis • Source: Dried leaves of Digitalis purpurea Linn • Family: Scrophulariaceae • Syn. : Purple foxglove, Lady’s glove, Finger flower • Histroy: The word purpurea has been derived from the purple colour of flowers • G.S.: England, Germany, France, North America, India, Iraq, Japan, Mexico, Spain, Turkey

Horses have been fatally poisoned after consuming 0.075% of their body weight of the plant. The alkaloids can be absorbed through the skin and may cause poisoning in humans handling the plant. • Mechanism of toxicologic damage. Aconitine-type diterpene alkaloids bind sodium channels, causing persistant activation. • Diagnosis • Clinical signs. Clinical signs are similar to those caused by larkspur poisoning. Within a few hours of ingestion, restlessness, and excessive salivation are seen. Animals develop muscle weakness and hypotension and have difficulty breathing. Eventually, affected animals will collapse in lateral recumbancy. Death may occur several hours to days postingestion due to either heart block and ventricular fibrillation or to respiratory failure. • Lesions. No lesions are seen. • Treatment. No treatment has been proven effective in monkshood poisoning. Affected animals should be stressed as little as possible. Symptomatic treatment with intravenous fluids may be helpful. Vomiting and diarrhea should be controlled. Oral activated charcoal and osmotic laxatives may be helpful to reduce absorption of alkaloids from the GI tract.
