General
Description : The herb is an erect
perennial, growing to four feet with pinnate, divided
leaves and clusters of small white or pink flowers.
It has a massive root system and short rhizomes. The
roots are a hairy, spindly mass and are collected in
the autumn from two-year-old plants.
Traditional uses :
Valerian has been found to strengthen
the heart and can sometimes reduce high blood pressure,
if it is caused by stress and anxiety. It encourages
ulcer and wound healing and, when used topically, is
effective for muscle spasms and menstrual cramps. As
an expectorant, it helps a tickling, nervous cough.
In South Africa, V. capensis, is used for hysteria and
epilepsy. In China, V. hardwickii, is used as an atispasmodic.
The Menominee tribe of North America, used V. ulginosa
for cramps and menopausal symptoms
while, in the Himalayas, V. wallichi is used in almost
exactly the same way.It has a relaxing nature is a benefit
to those unable to relax during stress-related periods
and in general has a more calming effect rather than
a sedating one. It is also beneficial in relaxing overcontracted
muscles and helpful for shoulder and neck tensions,
asthma, colic, and irritable bowel syndrome. For more
than a decade, it has been used to treat ADHD and researchers
have found it to be more effective than pharmaceutical
agents with fewer adverse side effects. Nervous spasms
and tremors, phobias, insomnia, and restlessness may
be helped by using the herb.
Phytochemistry
: The chief constituent of Valerian
is a yellowish-green to brownish-yellow oil, which is
present in the dried root to the extent of 0.5 to 2
per cen, though an average yield rarely exceeds 0.8
per cent. The root also contains two alkaloids - Chatarine
and Valerianine. The rootstock of Valerian has 150 phytochemicals
[plant-based] which are classified into least two (2)
primary compounds as well as other amino acid constituents
that are thought to exhibit a sedative effect in Central
Nervous System (CNS) . These include:
- Valerenic Acids (valerenic acid, hydroxy
valerenic acid, acethoxy valerenic acid and
valerenal).
- Valepotriates (valtrate, isovaltrate, acevaltrate,
didrovaltrate).
- GABA (Gamma-Aminobutyric Acid).
- Tyrosine, Arginine, and Glutamine.
Pharmacological research
suggests that together, these components naturally inhibit
enzyme-induced GABA (Gamma-Aminobutyric Acid) breakdown
in the brain, although, the precise mechanism of action
has yet to be defined.
Pharmacology :
The rhizome of valerian contains a variety of compounds
including valepotriates, valeric acid, and volatile
oils. These compounds affect brain receptors for the
neurotransmitter gamma-aminobutyric acid (GABA). Valerian
influences the cerebro-spinal system and has a sedative
effect for conditions such as St. Vitus's dance, neuralgic
pains, and insomnia by allaying pain and promoting sleep
without the aftereffects of narcotics .
Marker constituent
: Valerenic acid
Main Actions :
It is Anti spasmodic, Stimulant, Stomachic, carminative,
diuretic, hypnotic, hypotensive, relaxant, sedative,
warming, powerfully nervine.
Main Uses : Valerian
may be indicated for the relief of insomnia, stress-related
anxiety, and nervous restlessness. It may also be used
to ease stomach and menstrual cramps, irritable bowel
syndrome (IBS), some of the restlessness that accompanies
attention deficit/hyperactivity disorder (ADHD) and
migraine symptoms. It is also useful in diseases of
eye, blood, livers. And, more rarely, it may be used
to treat convulsions from a seizure disorder. In its
most well-documented use, however, it is used as a calmant
to help people sleep.
