As we age, it is natural for our energy levels to decline. In Chinese medicine, this is explained by the concept of Kidney Essence—the fundamental reserve of vitality we are born with. This essence determines our capacity to generate energy from food and air, supporting growth, fertility, resistance to illness, and recovery from injury.
Each person is born with a different amount of this reserve. From early adulthood, typically after the mid-twenties, it gradually declines in everyone. Healthy living can slow this process, but it cannot stop it entirely.
One traditional way of supporting vitality later in life is through the use of tonic herbs. In Chinese medicine, tonics are never used as single herbs or universal remedies. They are prescribed as carefully balanced formulas, tailored to the individual’s constitution, digestion, temperature sensitivity, and overall state of health.
This is why the common Western habit of taking isolated tonic herbs, such as ginseng, without proper assessment is considered inappropriate in Chinese medicine and may even be harmful for some people.
Classically, people over the age of fifty—particularly those who feel cold easily, have chronic digestive weakness, or are less robust—may benefit from taking a tonic formula during the winter months, when the body naturally turns inward and rebuilding is most effective.
If you are considering a winter tonic, it is essential to seek individual advice rather than self-prescribing. A short consultation can help determine whether a tonic is appropriate for you, and if so, which type would best support your health at this stage of life.

In Chinese medicine, the start of spring is based on the traditional Chinese solar calendar, which divides the year into 24 solar terms. The first solar term is called Lìchūn (立春), meaning “Beginning of Spring.” This marks the official start of spring in TCM and typically occurs around February 3rd or 4th, depending on the year. It is calculated based on the position of the sun. Lìchūn reflects a shift in energy from winter’s deep Yin (rest, stillness) to the gradual emergence of Yang energy (growth, renewal). It aligns with nature’s rhythms, where seeds begin to stir underground, animals awaken, and life starts to regenerate.
In the body springtime corresponds to the liver. In other words the energy (Qi) of the liver is both more active and more vulnerable in spring, and the flow and economy of the body’s energy (Qi) is particularly influenced by the liver at this time of year.
In Chinese medicine the Liver is responsible for several functions including regulating the smooth flow of Qi in the body, storing and regulating the supply of blood, supporting digestion, nourishing the ligaments and tendons, maintaining the health of the eyes, supporting and regulating the menstrual cycle.
Green is the colour associated in Chinese medicine with springtime and with the the liver. The green in plants is the pigment chlorophyll, an extraordinary molecule that uses sunlight as energy to transform carbon dioxide in the air to sugar and oxygen. Sugar provides energy for the plant’s growth, repair and metabolism. Chlorophyll contains magnesium, so green leafy vegetables are important sources of this mineral in our diet. Magnesium is essential for metabolism, much of which occurs in the liver, and this ties in with the liver’s function of regulating the flow of Qi in Chinese medicine.
According to Chinese medicine liver imbalances may give a range of symptoms depending on the kind of imbalance and the organs that are most affected by it because of your constitution or because of the specific circumstances at the time.
However, typical “liver symptoms” (what I call “liveriness”) include shoulder, neck tension and jaw tension, clenching or grinding the teeth at night, tension headaches, dizziness, an unpleasant feeling of heat inside or being too hot, intolerance of hot stuffy environments, premenstrual syndrome, menstrual pain and irregularities, irritability, quick temper, anxiety, depression, mood swings, rib pain that shifts, red and ichy eyes, eye issues in general. Liver imbalances can also manifest as poor digestion with discomfort and bloating, high blood pressure, high cholesterol, chronic skin problems, allergies, food intolerance and sensitivities, fatigue and lethargy.
But remember: don’t self-diagnose! Remember that although all of these are common liver symptoms, many of them may be caused by other kinds of imbalances too.See a qualified practitioner of Chinese medicine.
Here are six great herbs used by Western herbalists to support this vital organ. There are many others and each is unique in its characteristics and uses. Medical herbalists choose the right herbs to suit the individual person and condition.
Dandelion: The root is used to support liver function, while the leaves are diuretic and a great addition to salads too!
Gentian: The root is very bitter and is a wonderful digestive stimulant.
Artichoke: The leaves, stem and roots are used in herbal medicine to improve digestion and reduce cholesterol.
Burdock: Burdock root is a general depurative working on the liver and kidneys to expel toxins.
Fumitory: The above ground parts are used to treat issues arising from liver imbalances.
Milk Thistle: A liver tonic which protects the liver from toxins, including drugs used in cancer chemotherapy.
Traditional Chinese herbal medicine is great for liver imbalances! Traditional Chinese medicine never prescribes herbs singly, but in combination with other herbs that together make a balanced formula which treats a certain pattern of ill health. Over the past 3000 years a very large number of formulas have been developed in order to account for the many specific variations of the known disease patterns. Moreover, each formula can be varied by the practitioner by additions, subtractions, substitutions or modifications in the proportions of the different herbs.
Here is an example. It is an eight-herb formula called Xiao Yao San, variously translated as “Rambling Powder”, “Leisure Powder”, “Free and Easy Wanderer Powder”. The formulas tend to have poetic names! But the names are appropriate. Xiao Yao San is the most commonly used formula for what Chinese medicine calls Liver Qi Stagnation, and treats patterns that include several of the following symptoms: Anger, irritability, frustration or depression; a general feeling of “stress”, tension or anxiety; distension, pressure, discomfort or pain in the chest, rib cage or upper abdomen; neck and shoulder tension; jaw tension, grinding of the teeth; distension, lumps or swellings in the breasts in women; premenstrual syndrome, dysmenorrhea; constipation and/or diarrhoea, bloating, gas, loss of appetite.
IMPORTANT: Never self-diagnose or self-prescribe Chinese herbal formulas!
With regard to lifestyle, the things listed below are generally beneficial to the liver.
Green Leafy Vegetables and Bitter Greens like kale, collards, chard, spinach, beet greens, bok choy, rucola, chicory, dandelion.
Sour Foods like sour dough rye bread, sauerkraut, pickles, tart apples, grapefruit, lemons. While these are generally tonifying to the liver in small quantities, in larger quantities they are harmful, especially in spring. (More on the seasonal aspect of diet below.)
Cooling Foods: Traditionally plums, watercress, celery, mung beans and tofu have been used to cool Liver Heat. However, in spring if there are no heat symptoms, mildly warming vegetables are indicated instead, to align with the seasons energies (see below).
Mindful Eating: Eat slowly, calmly, avoid eating when stressed.
Relaxation and de-stressing: Meditation, yoga, taichi, walking in nature, creative activities.
Physical Exercise: Sport, gym, hiking, etc.
Stretching: A regular muscle stretching routine.
Sleep: Adequate regular restful sleep.
And these are things that may harm the Liver:
Chronic stress and supressed or repressed emotion: tension, frustration, resentment, anger
Poor diet: excess fatty or spicy foods
Drugs: alcohol, caffeine, recreational drugs, many pharmaceuticals.
Poor sleep: shallow or broken sleep, frequently waking during night
Sedentary lifestyle: lack of physical activity, too much sitting.
Toxins: environmental pollutants and work-related toxins e.g. varnishes, solvents.
Overwork: physical or mental strain.
Wind: exposure to strong wind for too long can agitate liver Qi (energy), while cold wind can disrupt ts proper movement.
Of course this has to be interpreted with common sense. Moderate alcohol or coffee consumption isn’t going to kill you. Brief exposure to a brisk wind may be energising rather than harmful. Pharmaceuticals are not the work of the devil, and taking them is always a balance between risks and benefits.
In spring when the Qi energy of the liver is most active, we need to support it by being especially kind to our livers! So far as diet is concerned, one of the oldest texts on Chinese medicine, The Yellow Emperor’s Inner Canon: Basic Questions (The Huangdi Neijing Suwen) recommends aligning the diet with the seasons. In the spring eat foods that support the free flow of Qi and the upward, outward movement of energy characteristic of the season: light, fresh, and mildly warm foods (e.g., young greens, sprouts, leeks), especially those with sweet and slightly acrid flavors (e.g., carrots, fennel, ginger). Young greens and sprouts align perfectly with the upward, outward movement of spring. Avoid heavy, greasy, and overly salty foods, which can stagnate the rising energy of spring.
For good overall health, make sure you are kind to your liver in Springtime!

Cognitive impairment affects many older adults. It covers everything from mild deficits in short-term memory to advanced dementia from various causes.
There has been much scientific interest in recent years in the role of inflammation in the development of dementia, and a new study shows that inflammation may increase the risk of developing Alzheimer’s disease and dementia by 35% [1].
A 2003 study of 251 plants used in folk medicine from all parts of the world found out that most of them reduce inflammation, and almost half of them possessed anti-inflammatory activity specifically for the nervous system [2].
I have found the combined use of the following herbals to be helpful in slowing cognitive decline. They include turmeric, which is an effective herbal anti-inflammatory, rosemary, which has a traditional reputation for improving failing memory, and herbs to improve blood flow in the brain and boost general vitality.
Ginseng (Panax ginseng): Boosts general energy level and brain function. Studies indicate that if ginseng is combined with ginkgo, its long-term effect on cognitive function in human volunteers is greater than either herb used alone [4].
Ginkgo (Ginkgo biloba): Improves blood circulation in the brain. Studies indicate that if ginkgo is combined with ginseng, its long-term effect on cognitive function in human volunteers is greater than either herb used alone [3].
Rosemary (Salvia rosmarinus): Traditionally used for memory decline; also boosts general energy levels.
Turmeric (Curcuma longa) taken with black pepper (Piper nigrum): Reduces inflammation, one of the processes thought to be involved in cognitive decline and dementia. Black pepper improves the bio-availability of turmeric.
Ashwaganda (Withania somnifera): Boosts general energy level and brain function.
One problem I come across when people fail to report benefits from self-prescribed herbal remedies, even if they are suitable for the problem and person, is that they simply have not been taking enough.
For the herbs listed above, as a general rule I would consider the following forms and dosages to be adequate:
Ginseng: As a tablet or capsule, 250 to 500 mg ginseng extract per day. Look for a standardised extract containing at least 4% ginsenoside.
Ginkgo: As a tablet or capsule, 120 to 240 mg ginkgo extract per day. Look for a standardised extract containing at least 24% flavone glycosides and 6% terpene lactones.
Rosemary: As a tincture (or gycerite if you cannot or do not want to ingest alcohol*): 5 to 10 mL per day in water. (5 mL = 1 teaspoon.)
Turmeric: As a tablet or capsule, 500 to 1000 mg turmeric extract per day. Look for a standardised extract containing at least 95% curcuminoids.
Ashwaganda: As a tablet or capsule, 250 to 500 mg ashwaganda extract per day. Look for a standardised extract containing at least 5% withanolides.
[* A tincture is an extract of the plant in a mixture of water and alcohol; a glycerite is an extract in water and vegetable glycerine.]
It is good practice, as a precaution against side-effects, to start with the lower dose for a month before increasing to the higher dose.
In order to achieve more stable levels of the chemical constituents of the herbs in the blood throughout the day, it is best to divide the above amounts into multiple doses. Three doses – morning, noon and evening – is a common scheme, but if the organisation proves difficult, two doses (morning and evening), though less effective, will suffice.
The use of herbs alone though is just one strategy to use to slow cognitive decline. Other dietary, nutritional, lifestyle and psychological factors should also be considered:
Keep physically and mentally active.
The diet should be high in fruit, vegetables, wholegrain cereals, legumes, with frequent consumption of fish, especially oily fish, and low in red meat and saturated fats.
Good hydration.
Only moderate alcohol consumption.
A recent meta-analysis (an analysis of the results of multiple studies) suggests that B vitamin supplementation is associated with slowing of cognitive decline [4].
Studies indicate that the personality traits of conscientiousness, agreeableness, openness and extraversion may be associated with a lower risk of developing dementia, while the trait of neuroticism (negative attitude and outlook) is associated with increased risk. Thus a positive, open, outgoing, kind and conscientious attitude is worth cultivating! [5]
