Hypericum
& Depression
*A report in the British medical Journal highlights the use of
Hypericum in the treatment of depression. Apparently, German doctors prescribed over 66
million doses of hypericum perforatum in 1994 and a review of 23 randomised clinical
trials of hypericum extracts showed them to be superior to a placebo in the treatment of
depressive symptoms.
The report acknowledges that hypericum "may offer an
advantage in terms of relative safety and tolerability" over traditional
pharmacological medicines. Furthermore, commercially available hypericum products are
relatively economical as the herb is cheap to grow and easy to harvest.
Vervain, lavender and borage are all traditionally used
nervine herbal remedies which can help counter depressed feelings. Ginseng is also
commonly used to help overcome depression. It is, of course, important to consult a
qualified practitioner to obtain the most effective course of treatment.
Psychiatric medications are notorious for
undesirable side effects to the patient's mental and physical well-being and
the need for safer antidepressants is now widely acknowledged. However,
researchers have recently discovered one natural herbal remedy which is
considered to be as effective as most traditional allopathic antidepressants
but with the added advantage of being free from side effects. The herb in
question is St John's Wort (Hypericum Perforatum).
St John's Wort was tested in a double-blind
study of 105 patients suffering from mild-moderate depression. The patients
were male and female , 20 to 64 years of age, and diagnosed as having neurotic
depression or temporary depressive mood. They were then divided into two
groups and monitored over a period of four weeks. One group were given 300mg
of St John's Wort extract, three times daily, and the other group were given a
placebo. All of the patients were given psychiatric evaluations before the
start of the study , and after two and four weeks of treatment.
The results revealed that, after the four
weeks, 67% of the Hypericum group had responded positively to the treatment
without any adverse side effects whereas only 28% of the placebo group showed
any signs of improvement.
The authors of the study state clearly that the
study was deliberately confined to patients affected by mild forms of
depression because, for those patients, the possible risks of traditional
antidepressants often outweighed any expected benefits. Indeed many patients
within that category were known to refuse medications because of the possible
side effects. Therefore, whilst there was no evidence to suggest that
Hypericum would be of any benefit to patients suffering from the more serious
forms of depression, in relation to the lesser but more common forms of
depression, the researchers recommend: 'Hypericum should be used as a remedy
of choice'.

St John's Wort (Hypericum) beats
depression
The number of visits to
alternative medicine practitioners in this country is estimated at 425
million, which is more than the number of visits to allopathic primary
care physicians in 1990. Patients' use of St. John's Wort (SJW) has
followed this sweeping trend. The purpose of our study was to examine
the reasons people choose to self-medicate with SJW instead of seeking
care from a conventional health care provider.
The researchers used open-ended interviews with key questions to elicit
information. Twenty-two current users of SJW (21 women; 20 white; mean
age = 45 years) in a Southern city participated. All interviews were
transcribed, and descriptive participant quotes were extracted by a
research assistant. Quotes were reviewed for each key question for
similarities and contextual themes.
Four dominant decision-making themes were consistently noted.
These were: (1) Personal Health Care Values: the patients had a history of
alternative medicine use and a belief in the need for personal control
of health; (2) Mood: all SJW users reported a depressed mood and
occasionally irritability, cognitive difficulties, social isolation, and
hormonal mood changes; (3) Perceptions of Seriousness of Disease and
Risks of Treatment: SJW users reported the self-diagnosis of
"minor" depression, high risks of prescription drugs, and a
perception of safety with herbal remedies; and (4) Accessibility Issues:
subjects had barriers to and lack of knowledge of traditional health
care providers and awareness of the ease of use and popularity of SJW.
Also of note was the fact that some SJW users did not inform their
primary care providers that they were taking the herb (6 of 22). Users
reported moderate effectiveness and few side effects of SJW.
SJW users report depression, ease of access to alternative
medicines, and a history of exposure to and belief in the safety of
herbal remedies. Users saw little benefit to providing information about
SJW to primary care physicians.

Hypericum & depression - a review
Depressive
disorders are often found to be chronic and recurring illnesses that
lead to severe
personal suffering for sufferers and their families. Major depression alone is
estimated as the fourth most important cause of worldwide loss
in disability-adjusted life years and is considered likely to become the
second most important
within 20 years. A continued quest for more effective treatments has spawned newer
antidepressants and herbal treatments, which have contributed to explosive growth in
antidepressant prescribing, increasing pharmacy costs, and wider choices for
clinicians and patients.
A comprehensive evaluation of the benefits and
adverse effects
of newer pharmacotherapies and herbal treatments for depressive disorders in adults
and children was undertaken..
Literature published between 1980 to January
1998 was identified from a specialized registry of controlled trials, meta-analyses,
and experts. The registry contained trials addressing depression
that had been identified from multiple electronic bibliographic databases, hand
searches of journals, and pharmaceutical companies. The search, which yielded 1,277
records, combined terms "depression," "depressive disorder," or
"dysthymic disorder" with a list of 32 specific
"newer" antidepressant
and herbal treatments.
Randomized
controlled trials
were reviewed if they (1) were at least 6 weeks in duration; (2) compared a
"newer" antidepressant with another antidepressant (newer or
older), placebo,
or psychosocial intervention; (3) involved participants with depressive disorders;
and (4) had a clinical outcome. 315 trials that met these criteria.
Data was independently abstracted from each
trial by two persons. The researchers looked at the response rate, total
discontinuation rates
(dropouts), and discontinuation rates due to adverse events. Response rates were defined as
a 50 percent or greater improvement in symptoms as assessed
by a depression symptoms rating scale or a rating of much or very much improved as assessed
by a global assessment method.
There were 264
trials that evaluated antidepressants in patients (adults and children) with major depression.
Of these, there were 14 trials evaluating hypericum (St. John's wort), and a review of
these studies revealed that the herb was more effective than
placebo in treating mild to moderately severe depressive disorders (risk
ratio 1.9, 95% CI 1.2
to 2.8). However, the question as to whether hypericum (St. John's wort)
is as effective
as standard antidepressant agents given in adequate doses was not established.

Aromatherapy
& Depression
Aromatic oils have
been used for literally thousands of years in healing; for instance, lavender oil was used
in ancient Egypt for healing skin complaints and Eucalyptus oil has been used for
centuries to help clear sinus congestion. However, recent research by Dr G Schwartz,
professor of Psychology and psychiatry at Yale University, revealed that certain aromas
can even lower blood pressure. Some oils have been shown in research to have analgesic
(pain reducing) qualities whereas others have been shown to be antibacterial, antiseptic
and anti-inflammatory. Clinical trials have shown essential oils to be beneficial in
alleviating labour pains, reducing emotional stress, improving circulation, and even in
helping patients with mental disorders. (1)
The essential oils have a complex action on the body which
is still not fully understood. This may be due to the fact that one oil can have hundreds
of different compounds. Interestingly, your sense of smell is over 10,000 more sensitive
than your sense of taste and researchers have shown how aromas cause a brain reaction,
activating the hypothalamus gland, the pituitary gland and the body's hormones as well as
stimulating the limbic system (centre for emotion and memory) in the brain.
Work carried
out by Dr. Gary Schwartz, Professor of Psychology and Psychiatry at Yale University, found
that the aromas of some essential oils by themselves affect the nervous system and even
reduce blood pressure. The calming and relaxing effect of the essential oils and massage
can help relieve accumulated tensions and anxieties.
The following essential oils are also beneficial in the
treatment of depression as they have properties helping to balance and relax the nervous
system .
Chamomile - relaxant and calmative
Clary Sage - antispasmodic
Cypress - anti-spasmodic
Lavender - relaxant and calmative
Marjarom - emotional balancer
Rose - anti depressant
Rosewood - calmative
Ylang Ylang - sedative and antidepressant
The therapeutic massage combined with selected essential
oils makes aromatherapy an excellent aid in countering the effects of stress and inducing
relaxation. Massage improves the blood circulation in several ways without putting
additional strain on the heart. It helps the flow of blood through the veins and also
stimulates the nerves which control the blood vessels. It has the added benefit of
relaxing tense muscles and tight connective tissues which may have been constricting blood
vessels and thus enabling blood to flow more freely. It is for this reason that soothing
massage helps reduce emotional tension, it induces relaxation and calms stress-related
cardio-vascular conditions.
In fact, massage treatment alone has been shown to be an
effective treatment to help patients with depression. In one study conducted at the
University of Miami, 52 teenagers hospitalised for depression were split into two groups.
For 5 days, the first group were each given a 30 minute massage and the second group
watched television. The massage group felt less anxious, more co-operative, had lowered
pulse rates and lower levels of cortisol ( a chemical produced under stress) in their
saliva.(3)
Guidelines for using aromatherapy essential oils: -
Essential oils can be used at home in one of the following ways:-
Massage - mix 5 -10 drops to 10 ml of a vegetable base oil.
Baths - add 5 -10 drops to a pre-run bath and swish.
Inhalation - add 2 - 3 drops to a bowl of steaming water, cover head with a towel.
Tissue - put one drop on a tissue and inhale when required.
Room - put between 1 - 10 drops in a humidifier filled with water or on a piece of cotton
wool and place on a radiator.
IMPORTANT NOTE: Do not take any oils internally or use on
babies under 18 months. Always consult a qualified aromatherapist before using any
essential oils to treat a health problem, or if you are pregnant or breastfeeding.

Acupuncture
& Depression
Acupuncture has traditionally been successfully employed in China to treat most
illnesses. There are several controlled medical studies confirming that acupuncture is an
excellent therapy in the treatment of depression.
In one study in Italy involving 50 patients, auricular
acupuncture (acupuncture treatment to the ear) was found to be effective in reducing
anxiety and depression levels (1) . In another study at the Wayne County General Hospital
in Michigan, USA, acupuncture treatment was given to 85 patients all suffering from
psychological disorders (including depression). The treatment was shown to be beneficial
in over 78% of the patients. (2) There is therefore little doubt that acupuncture is a
prime therapy to consider in helping overcome depression.
Traditional acupuncturists treat the whole person rather
than a disease and therefore attempt to get to the root cause of the problem rather than
treating the symptoms and, like other holistic practitioners, will consider all lifestyle
and environmental factors before commencing treatment.

Acupuncture is not commonly associated with mental depression, but researchers at Institute of Acupuncture and
Moxibustion, China Academy of Traditional Chinese Medicine, Beijing recently demonstrated that acupuncture may offer a therapeutic option for depressive patients.
Twenty patients suffering from mental depression were treated by needling at the extra channel points for a period of six weeks and the effective rate of the treatment was found to be 90%. At the same time, the researchers monitored a control group of an additional twenty one depressive patients who were treated with amitriptyline. Anxiety, cognitive disturbance, retardation, sleep disturbance and feelings of despair were all measured with Hamilton's scale and then analysed.
The results showed that there was no statistical difference in the response rate in the two groups. Both the acupuncture and control groups showed an obvious decrease in the mean value, and the change in anxiety somatization was considerably greater in the acupuncture
group as compared with that in the control group. Analysis of brain wave patterns demonstrated that the acupuncture treatment had a positive influence on the patients’ brain waves.
The researchers concluded that six weeks of acupuncture resulted in s decrease of slow wave delta and increased the fast wave alpha , all significantly different as compared
with that before and during the treatment.
It would have been helpful in interpreting the results if the researchers had used a third control group so that a placebo treatment could be included. However, despite this omission, and the obvious small numbers of participants, the study does demonstrate that acupuncture treatment may be a useful treatment to considered to help treat patients suffering from depression, and will initiate further research in this area of medicine.

Recent research has found that cerebral serotonin has anti-depressant and analgesic effects and there have ben reports that cerebral serotonin can be released
by the stimulation of certain acupuncture points. Researchers at the Department of Anesthesiology, Wayne County General Hospital, Westland, Michigan, USA investigated these claims, observing the effects of sequential electric acupuncture treatment on eighty five (85) patients diagnosed with chronic physical disorders (e.g. intractable pain, headache) with most disorders complicated by reactive depression. Some of the patients’
problems were thought to be psychosomatic. However, the researchers found that the percentage of improvement from slight to remarkable in the physical disorders was 77.1% and the improvement seen in mental disorders was found to be even higher at 78.8%. The researchers concluded that sequential electrical stimulation to certain acupuncture points was found to be effective in the treatment of stress related physical and mental disorders.

Yoga & Meditation
& Depression
Yoga is a complete science, focussing on breathing, movement,
posture and meditation. Specific exercises are taught consisting mainly of simple
stretching, breathing and relaxation. There is a wealth of scientific research available
confirming that advanced yogis have remarkable control over the functioning of their
nervous system, heart and lungs. Subjects have demonstrated their ability to drastically
reduce their heart beat and respiration for hours at a time under clinical studies. In one
study involving 3,000 yoga students carried out by the Yoga Bio-Medical Trust (Cambridge,
England), 84% of those people who were suffering from hyper-tension (and there were 150 in
number), claimed that they had benefited from the practice of yoga. Controlled trials have
confirmed that yoga promotes vitality and is effective in management of heart conditions,
including high blood pressure.
Meditation and yoga are very gentle and powerful techniques
to aid rest and relaxation whilst energising the body. In fact, Dr Bernie Segal, author of
the best-selling 'Love, Medicine and Miracles' states that even for patients with cancer
" I know of no other single activity that can by itself produce such a great
improvement in the quality of life" (p149).
Dr Segal also cites the research of Dr Herbert Benson
showing that meditation tends to normalise blood pressure, pulse rate, and level of stress
hormones in the blood. It produces changes in brain wave patterns, showing less
excitability and improves the white blood cell (immune) response as well as hormone
response. It therefore must be considered as a vital and easily accessible aid to
stimulate and augment recovery for patients suffering with depression.
Meditation : - Researchers at the School of Behavioural Sciences, James Cook University of North Queensland, Townsville, Australia recently demonstrated that meditation has an observable and measurable influence on both our hormone levels and moods which is similar to the changes experienced by long distance runners.
The researchers studied the relationship between three hormones ( hypothalamic-pituitary-adrenocortical axis, beta-endorphin , corticotropin-releasing hormone
and cortisol and mood changes in 11 elite runners and 12 highly trained meditators who were all matched in age, sex, and personality.
Interestingly, the results revealed that despite the obvious metabolic differences between running and meditation, both of these activities produced similar hormonal changes. Compared to pre-test and control values, the subjects' moods were shown to be elevated after both activities with no significant difference between the two groups. Running produced significant elevations of beta-endorphins and corticotropin-releasing hormone, and meditation produced similar elevations in corticotropin-releasing hormone. When the results of the two groups were compared, there was found to be no significant differences between the respective influences on hormone levels and moods . The researchers concluded that both running and meditation have a positive influence on participants' moods which is thought to result from changes in plasma levels of corticotropin-releasing hormone which occur after both activities.

Light Therapy
& Depression
Scientists at the Department of Psychiatry, St. Goran's Hospital, Stockholm,
Sweden monitored ninety patients with major depressive disorder who were
classified according to seasonal depression (60 patients of which 50 were
women) and non-seasonal (22 patients of which 17 were women). All of the
patients were also clinically evaluated and rated before and after morning
(0600-0800) or evening (1800-2000) light treatment for ten days in a room with a
luminance of 350 cd/m2 (approximately 1500 lx) at eye level. The patients’
mood ratings were assessed using both the Comprehensive Psychopathological
Rating Scale and the Hamilton Depression Rating Scale.
The results showed that depressed patients with
seasonal pattern improved significantly more than those with a nonseasonal
pattern suggesting a specific therapeutic effect of light treatment in depressed
patients with seasonal pattern. There were no significant differences in outcome
when light treatment was given in the morning or in the evening, and neither
were there differences between patients with and without atypical symptoms such
as carbohydrate craving or increased appetite.
Researchers at the University Hospital, State University of
New York (3) found that variability in pain intensity, demoralization and
range of mandibular motion among patients suffering from myo-fascial face
pain is associated with seasonal variations.
Evaluating 273 patients whose
conditions were measured in each of 10 monthly interviews, the researchers
found that the patients’ pain intensity and demoralization were
significantly greater in the peak dark months than in the peak light months.
The researchers concluded that the data suggested that myo-fascial ( face)
pain and depressed moods are related and may be affected by common risk
factors including seasonal variations relating to the number of light hours
in the day.

Music Therapy
& Depression
Music therapy has been put forward as a cost-effective and accessible
intervention for older adults experiencing symptoms of depression, distress,
and anxiety. Researchers at Stanford University School of Medicine, USA
monitored thirty older adults who had been diagnosed
with major or minor depressive disorder. The participants were randomly
assigned to one of three eight-week
conditions: (1) a home-based programme where participants learned music
listening stress reduction techniques at weekly home visits by a music
therapist; (2) a self-administered programme
where participants applied these same
techniques with moderate therapist intervention involving a weekly telephone
call; or (3) put on a waiting list and
used as a control.
The results showed that the participants in
both music conditions performed significantly
better than the controls on standardized tests of depression, distress,
self-esteem, and mood. These improvements were clinically significant
and, the researchers noted that these benefits
were maintained over a nine-month follow-up period.
The researchers concluded that there was great potential for music
therapy as a beneficial intervention especially for homebound elderly people
and others who have limited access to health care professionals.

Exercise
& Depression
It is now well known that physical exercise can alter hormone levels within the body and have a positive effect on our moods, however new research has demonstrated that meditation offers similar benefits. Researchers at the School of Behavioural Sciences, James Cook University of North Queensland, Townsville, Australia studied the relationship between three hormones (hypothalamic
pituitary adrenocortical (HPA) axis, beta-endorphin (beta-EP), corticotropin
releasing hormone (CRH) and cortisol) and mood changes in 11 elite runners and 12 highly trained medidators matched in age, sex, and personality.
Despite the obvious metabolic differences between running and meditation, the researchers predicted that mood change after both of these activities would be similar if they could be associated with similar hormonal changes. Compared to pre-test and control values, mood was shown to be elevated after both activities but there was no significant difference between the two groups. There were significant elevations of beta-EP and CRH after running and of CRH after meditation, but no significant differences were seen in the increases in CRH levels between the groups. CRH was found to be directly related to positive mood changes after running and mediation. Cortisol levels were also noted to be generally high but erratic in both groups.
The researchers concluded that both running and meditation have a positive effect on our moods which is associated with the changes in relation to plasma corticotropin-releasing hormone.

Electro-acupuncture
& Depression
Electroacupuncture
(EA) stimulation has been found to influence the brain (norepinephrine
metabolism in experimental animals). Preliminary clinical research has shown
that EA treatment is as effective as amitriptyline for patients with depression.
In this study, two consecutive clinical studies on the
treatment of depression with EA are conducted. The first study was double blind
placebo controlled, in which 29 depressed inpatients were recruited. Patients
were randomly divided into three groups: EA + placebo; amitriptyline; and EA +
amitriptyline. They received EA and/or amitriptyline treatment for 6 weeks. The
Hamilton Rating Scale for Depression, Clinical Global Impression and ASBERG
scales for the side effect of antidepressants were used to evaluate the
therapeutic efficacy and side effects. Based on the results and research
protocol of the first study, a multi-centered collaborative study was conducted,
in which 241 inpatients with depression were recruited. Patients were randomly
divided into two treatment groups: the EA + placebo and the amitriptyline
groups. The results from both studies showed that the therapeutic efficacy of EA
was equal to that of amitriptyline for depressive disorders (P > 0.05).
Electro-acupuncture had a better therapeutic effect for anxiety somatization and
cognitive process disturbance of depressed patients than amitriptyline (P <
0.05). Moreover, the side effects of EA were much less than that of
amitriptyline (P < 0.001).
The report suggested that EA treatment was an effective
therapeutic method for depressive disorders. Particularly, it was a treatment of
choice for depressed patients who were unable to comply with the classic
tricyclic antidepressants because of their anticholinergic side effects.
