Green tea

Green Tea - Camellia sinensis

tea

Green tea is a popular health promoting tea, enjoyed all over the world.

Black, Oolong and Green tea all stem from the same plant, Camellia sinensis, however differences in processing results in three very distinct products not only in taste but also in health benefits. Green tea is the least processed and therefore isn’t exposed to oxidation, resulting in a tea that retains more antioxidants. The specific antoxidants found in green tea include catechin, epicatechin, epicatechin gallate, epigallocatechin gallate and proanthocyanidins.

In different parts of Asia, the tea is harvested at different times according to tradition. In Japan, only one cultivar of Camellia sinensis is used, the Yabukita variety, and the leaves are harvested any time from late spring all the way through until autumn - giving the leaves more time to grow on the plant.  In contast, in China, many varieties are used and the green tea is only harvested in the early spring, meaning the leaves have less time to grow. Not only the leaves are plucked, but in China the spring buds of the plants are also harvested. The Chinese method of drying the leaves uses a pan to dry fire them, or they might be oven dried or dried under the sun. The tea is then hand processed with workers rolling the tea leaves into shapes - such as balls, twists, spirals and swords.  Green tea is traditionally only brewed for 2-3 minutes and if you leave it longer it can be quite bitter and higher in the astringent tannins.

Genmaicha - Japanese green tea with roasted rice

Some Japanese Green Tea can also contain twigs and roasted puffed rice along with the green tea, the popular variety is referred to as Genmaicha. Kyoto was the birthplace of genmaicha, where legend tells of a tea farmer who mixed roasted brown rice (as a filler) in with his cheapest blends of green tea so that even poor people could afford to buy his tea, and get some extra nutrients along with the tea. Genmaicha has a milder nutty flavour combining the fresh grassy flavor of green tea with the aroma of the roasted rice and it became a popular brew in time. Tea steeped from genmaicha has a light yellow hue and It is traditionally brewed for 3-5 minutes.

What it’s good for

Anti-Ageing

Green tea contains a potent range of antioxidants responsible for fighting a prime culprit in the ageing process; free radicals. Epigallocatechin gallate, a green tea polyphenol now incorporated into many skin care formulations, has been shown to reduce damage done to skin cells and is proported to offer antioxidant protection against mild sun exposure.

Cancer

Green tea has been shown in several studies to decrease proliferation of cancer cells and it can also increase apoptosis, which is what we call the highly regulated process of inbuilt cell death. Many cancer cells lose their innate programming for cell death and thus keep growing and spreading. Agents that can stimulate this process of apoptosis can lead to reduced cancer cell numbers. Epigallocatechin gallate was found to reduce the risk of skin cancer through its protection against UV radiation. Topical application of green tea half an hour before skin exposure was shown to be protective against sunburn. Systematic scientific studies and research suggest green tea possesses protective capabilities against breast, prostate and upper gastrointestinal tract cancers.

Weight Loss

Green tea consumption has been associated in several studies with moderate weight loss, reduced weight circumference and metabolic parameter improvements when combined with regular exercise. Animal studies found this weight loss to be due to decreased leptin (dubbed the obesity hormone), decreased food intake and an increase in metabolic rate due to increased thermogenesis. Green tea also contains caffeine which has a subtle stimulating impact on weight loss, but usually not strong enough on its own to exert much impact.

Memory and Mood

Matcha powder is rich in L-theanine, an amino acid that is good for anxiety and stress.

Green tea intake has been shown to significantly improve cognitive performance and learning ability with long-term consumption. This is thought to be due to a combination of improved cerebral blood flow and the neuro-protective effects of L-theanine, a compound found in green tea. L-theanine exerts this action through modulation of our neurotransmitters GABA and glutamate. Despite these neurotransmitters being cut from the same cloth, GABA and glutamate have opposing effects in the body. Glutamate is an excitatory neurotransmitter and is often released by the body in times of stress. GABA on the other hand is an inhibitory neurotransmitter and when released has a calming effect on the body. L-theanine works by blocking the glutamate pathway, in turn increasing GABA. Incorporating green tea into your diet is a nice way to gently reduce the effects of glutamate but for those suffering from anxiety and stress a supplemental dose of L-theanine would be more beneficial. I have found using an actual capsule of concentrated  L-theanine can be an effective supplement for anxiety and tension in my patients.

What it’s not good for

  • Due to its caffeine content, high intake of green tea may increase central nervous system (CNS) stimulation of drugs such as nicotine and salbutamol and conversely reduce drug effects of CNS depressants such as benzodiazepines.
  • Green tea contains high amounts of tannins that are capable of binding to and reducing the absorption of iron and other minerals. Caution in iron deficiency and iron supplementation should be exercised.
  • Caffeine content of green tea may effect blood glucose, monitoring in diabetes is advised
  • Due to its caffeine content, green tea may exhibit a diuretic effect, so ensure you drink an extra glass of water for each cup of tea consumed.

Here is a guide to all the different types of green tea with some of the benefits and highlights to choose from when selecting the best one for you.

Excessive intake of anything, even something that is seemingly good for you, is indeed not good for you. Drinking 3-4 cups of green tea per day is sufficient to get the beneficial effects according to the research. I also recommend combining green tea with other herbal teas that can have additional medicinal benefits for your individual needs.

Drinking very high doses of any caffeinated beverage including green tea is unsafe and can cause major health issues due to caffeine content.

 

 

Placebo effect

It’s all in the mind….exploring the power of the placebo effect

pillThe placebo effect is a term used to describe the benefit someone derives from taking a ‘medicine’ that is, in fact, not a medicine.  When people take something they believe to be a medicine, the power of their belief causes a shift in their thinking which then in turn can influence the physiology of the body.

In 1955, the scientist Henry Beecher published the classic work entitled “The Powerful Placebo” and he was the first scientist to define the placebo effect. Since that time, the placebo effect has been considered a scientific fact and the placebo or ‘dummy’ pill has been used to test the validity of drugs and treatments.  Unless a drug exhibits effects that are greater than the placebo, the drug is not considered effective. This powerful effect can be as high as 30-40% in some cases. Depression for example, has a fairly high placebo rate – with many people reporting improvements in mood whilst taking the placebo pill.  Other researchers have found that 85% of the effectiveness of cough syrups can be attributed to placebo, leaving only a tiny 15% to be active medicine. Side effects have even been reported in healthy volunteers taking placebo pills during clinical studies.

Research has been conducted for quite a few years into the placebo effect and how we might harness this in medicine.  After all if people can get better taking a dummy pill, then why don’t we use this effect more often? Placebo pills are biologically inactive and are thus safe and (should) have no side effects!

positiveSo why does the placebo pill work?  Our beliefs and expectations can influence and modulate activity in areas of the brain that are involved with perception, pain and the processing of emotion.  Researchers have shown that our mental processes such as thoughts, feelings and beliefs as well as our will and intention can significantly influence brain function.   Once upon a time, science viewed the way the brain functions as rigid and difficult to influence - especially in adulthood. However, we now know that the brain is far more open to influence and change and is in fact not rigid but quite ‘plastic’.  The term ‘neural plasticity’ has been coined to represent the fact that brain function is malleable and open to influence by our own subjective intention.  Once we have control over the master organ – we then have far more control and influence over the rest of the body’s functions.

So if we can positively influence our physiology through the ‘placebo’ effect – is it possible that we can negatively influence our body function through negative thinking?  This has, in fact, been shown to be true and has been given the term the ‘nocebo’ effect.  The nocebo effect has been scientifically proven, showing that with negative messages and verbal suggestions a patient can experience a worsening of their disease experience and outcome. It is not all just in the mind either – as blood tests shown increased inflammatory and pain markers after a nocebo procedure.

drpatEven when someone is given a diagnosis of illness – particularly serious or life threatening illness – the nocebo effect can start to operate.  This is why I find it counterproductive when well-meaning medical specialists tell a patient that they have “3 months to live” or they give similar limited predictions and opinions.  Research has shown that the anxiety and stress that this causes can negatively influence pain, immunity and mood – and go on to negatively influence the disease progression.

Another aspect of this mind over matter business is when a person creates an illness. In these cases, that despite the inconvenience and suffering of the disease, the experience is giving the patient some other positive reward.

I love bringing mind-body aspects into healing as it can really support healthy outcomes. Helping people to see how their thinking and beliefs influence all aspects of their physical health and subjective experiences is really rewarding. Even asking the question how their disease may be benefiting them often brings many insights and shifts.

So if we have a choice to influence our physical reality with positive or negative thinking and beliefs – then why not focus on the positive!

herb trial

Are you or a friend experiencing anxiety or depression?

You are Invited to Participate in a Herbal Medicine Clinical Trial

Karen is a lead practitioner in an ongoing research project that is evaluating the effectiveness of herbal medicine on the management of depression and anxiety. 
chamomileThe research is being jointly conducted by Endeavour College of Natural Health and the University of Technology Sydney and sponsored by Mediherb.
Herbal medicine offers a very effective tool for the management of mild to moderate depression and anxiety. Karen uses over 20 medicinal plants that have both research and clinical effectiveness for the treatment of mental health issues. Mental health issues such as depression and anxiety are increasingly common in our modern busy lives and can have a major impact on our quality of life, happiness and wellbeing. Utilising natural and effective herbal medicines can make a big difference and do not come with the standard side effects of mainstream drugs.

Your Medicine Costs Will Be Covered

The research data in this trial will be gathered over 3 consultations and any herbal medicines prescribed will be free of charge to the study participants for the three sessions. The study allows for flexibility of prescribing as the researchers are seeking to test the therapies as they are practised in the ‘real world’ by naturopaths.  Any of the medicines that Karen prescribes during your consultation to support your treatment aims will be dispensed and mailed out to you free of charge after your consultations.

Who is eligible for treatment and participation?

Holy Basil - a great herb for supporting the adrenals and nerves.

Holy Basil - a great herb for supporting the adrenals and nerves.

Only new patients or exisiting patients who I haven't recently treated for anxiety or depression will qualify. You must be experiencing depression or anxiety that has either been previously diagnosed medically or if you have a sense that you are experiencing mild to moderate depression or anxiety that is affecting your quality of life in some way, you are eligible to participate.

What if I am on medication already?

You can already be on pharmaceutical medication for depression or anxiety and still participate. There are some herbs we need to be careful not to prescribe in combination with various medications, but there are many more which can be used and could possibly improve medication outcomes.  Karen is highly experienced at managing these conditions with herbal medicines and also complimenting treatment with standard therapies when necessary.

What is the benefit for me?

While the regular consultation fee is charged for your three consultations, if you participate in the trial, you will receive your herbal medicine prescription free of charge as consideration for completing the necessary forms for the three consultations which are part of the study. Your treatment will still be personalised and prescribed on your individual needs and not be standardised to be the same for everyone. This is important research as it reflects how we use herbs in our naturopathic practice in an everyday application.
All going well, you are also highly likely to experience a positive change in your mental health! 

If I say "Yes", what will it involve?

lemonbalmIf you wish to be involved, you will need to commit to three consultation sessions which will be between 1-4 weeks apart, depending on the patient. The research component will only take a small amount of your time in addition to your consultation. You will have to complete five forms initially (one demographic form and four assessment questionnaires) at the initial consultation. After that there are four forms (the assessment questionnaires only) to be completed at the two subsequent follow-up consultations. These forms will take about 15 minutes to complete and will help to gather data to illustrate how the treatment is going. Due to the personal nature of this topic, some questions might make some people feel slightly embarrassed or uncomfortable, but are important for the treatment to be properly evaluated.
Karen will also provide detailed information about the herbal medicine treatment provided at each consultation and general advice on stress management and lifestyle.

What is the next step if I want to be involved?

You can learn more information about the study by visiting this website: http://herbsonthehill.com.au/anxiety-and-depression-study
If you would like to be involved, you can simply book online an appointment with Karen via clicking online bookings at either Buderim or Noosa clinics. 
Or you can call the Noosa clinic on 5449 7088 for Noosa bookings.
Just book a regular appointment if you are an exisiting patient or an initial appointment if you are a new patient. Please make sure you mention in the booking notes or to the receptionist that you wish to be involved in the trial, so the necessary paperwork can be prepared for you.  You will need to arrive a little earlier to fill the forms in, or they can be emailed out to you.
Here are some background forms for you to peruse about the trial before making your decision.

Looking forward to helping your heal with herbal plant power!

To me Karen is an absolute angel! I highly recommend Karen to anyone who is going through the whole ‘roller coaster’ journey of IVF. It was so lovely to actually have someone that actually listened to me, it was in 2010 when we decided we would give IVF one last go before having a break. Karen put me on a super tonic which I call her ‘magic potion’ and after a few weeks in taking this my FSH levels dropped dramatically and this was my lucky month and my dream had finally came true. I always feel so positive every time I leave Karen’s rooms, I’m so glad that I found her I can never thank her enough for my positive out come!
