CONTRAINDICATIONS
Contraindications to internal use include inflammatory
illnesses of the gastrointestinal area or of the biliary ducts,
and severe liver diseases.

PRECAUTIONS AND ADVERSE REACTIONS
General: No health hazards or side effects are known in
conjunction with the proper administration of designated
therapeutic dosages. The internal administration of Niauli oil
as a drug leads, in rare cases, to nausea, vomiting and
diarrhea.

Drug Interactions: Niauli oil contains 35-60% cineole.
Cineole causes the induction of the enzymes involved in the
detoxification of the liver. The effect of other drugs can
therefore be reduced and/or shortened.

Pediatric Use: Preparations containing the oil should not be
applied to the faces of infants or small children, since glottal
spasm, bronchial spasm and asthma-like attacks are possible,
as is respiratory failure.

OVERDOSAGE
Overdosages of Niauli oil (more than 10 gm), can lead to
life-threatening poisonings due to the high cineole content.
Symptoms include, among others, fall in blood pressure,
circulatory disorders, collapse and respiratory failure. In case
of poisoning, vomiting should not be induced because of the
danger of aspiration. Following administration of activated
charcoal, the therapy for poisonings consists of treating
spasms with diazepam (i.v.). treating colics with atropine,
electrolyte substitution and treating possible cases of acidosis
with sodium bicarbonate infusions. Intubation and oxygen
respiration may also be necessary.

DOSAGE
Mode of Administration: The oil and other galenic prepara-
tions are for internal and external application.

Preparation: Oily nose drops are prepared in a 2 to 5%
concentration in vegetable oil. For external use, preparations
contain 10 to 30% active ingredient in oil.

Daily Dosage: For internal use, the single dose is 0.2 gm,
with the daily dosage ranging from 0.2 to 2.0 gm.

Night-Blooming Cereus
Selenicereus grandiflorus
DESCRIPTION
Medicinal Parts: The medicinal parts are the fresh or dried
flowers, the fresh young stems and flowers, and the fresh
young shoots and sprouts.
Flower and Fruit: The flowers are 18 to 25 cm long and
have a diameter of 15 to 27 cm. They have numerous, long-
acute, lanceolate tepals that are arranged in a spiral. The
outer tepals are brown; the middle ones are light yellow and
the inner ones are spatulate to acute, lanceolate and snow
white. The numerous stamens are white and have yellow
anthers. The styles with the 4-rayed stigmas become yellow
toward the top. The ovary is globular and bumpy, with
triangular scales and many brownish-gray hairs and thorns,
which are approximately 10 mm long, dark brown and
bristly.
Leaves, Stem and Root: The plant has a succulent trunk as
well as a 1 to 4 cm thick snake-like, creeping or climbing,
branched stem, which can grow to 10 m long or longer. The
stem is 4- to 8-sided, green to bluish, has no bumps and is
covered in adventitious roots. It has white tomentose axis
buds on the protruding vertical ribs with 6 to 11 needle-like
thorns that are 4 to 6 mm long.
Characteristics: The plant has sweet-smelling flowers,
which only bloom for about 6 hours before dying.
Habitat: The plant is indigenous to Central America and is
cultivated in Mexico and also in Europe.
Production: The young shoots and flowers are harvested in
June or July and then preserved in alcohol. Some cultivated
production is done in greenhouse settings, particularly in
Europe.
Not to be Confused With: Confusion can arise with the
flowers of Opuntia maxima, Selenicereus hamatus, and
Selenicereus pteranthus. The drug is adulterated commercial-
ly with the flowers of Opuntia vulgaris and Opuntia ficus-
indica.
Other Names: Sweet-Scented Cactus
