What is Jing?

Jing is one of the most important concepts in Chinese medicine, where it’s traditionally said to be involved in every phase of life, from prenatal development right through to old age. But what exactly is Jing? And how can you look after and conserve yours?

tcm and kidney

In traditional Chinese medicine (TCM), Jing or essence is a substance that you inherit from your parents at the moment of your conception.

It subsequently fuels your growth and development as the pregnancy progresses and continues to do so throughout your infancy, childhood and adolescence.

Even after you stop growing and maturing, your Jing is the driver of your transition and transformation throughout your early adulthood, middle age and ultimately your senior years.

In short, Jing dictates your constitution and vitality as you move through each of life’s stages.

Because it occurs in different forms and is referred to several names (including ‘essence’ and ‘kidney essence’), Jing can be confusing to wrap your head around at first if you’re not familiar with the ins and outs of Chinese medicine.

The key thing to be aware of is that it’s a precious and valuable substance that should be guarded and protected in order to maintain your health and wellbeing, now and in the future.

Why Jing is like a bank account

You might like to think of Jing as being similar to a sum of money that your parents put into a bank account for you when you were conceived.

It’s a bucket of energy that’s intended to last you for your whole life – but it’s quantity varies, and some people get larger amounts of Jing than others.

While it’s okay to access some of that inherited energy from time to time, its balance would decline quickly if you constantly did that without topping it up.

The smarter thing to do is to add to the balance by making your own deposits, and only draw down on the original deposit when you absolutely have to.

In the case of Jing, you top up your inherited balance by acquiring additional Jing from substances in the food and drink you consume and the air that you breathe. That acquired Jing can then be used to nourish the organs, and any of it you don’t need immediately is stored in the kidneys so it’s available later.

Nevertheless, over the course of your life, you’ll repeatedly need to draw on your bank of inherited Jing, so as you get older its balance declines.

What does Jing do?

Jing’s major physiological roles in TCM include:

  • Growth and development: Jing stimulates all aspects of growth and development and the physical transformation that occurs at each life stage
  • Reproductive capacity and sexual function: Jing governs all aspects of sexual function and reproductive capacity (including puberty, fertility and women’s transition into menopause)
  • Healthy ageing: Maintaining optimal levels of Jing leads to healthy ageing in TCM
  • Facilitating blood production and therefore bone health and brain function: In TCM, it’s traditionally believed that the Jing is infused into the bones, and there stimulates both bone growth and the development of the bone marrow, brain and spinal cord
  • Maintaining strong defences against illness: When Jing is abundant, overall vitality will be too, including that of Defensive Qi, the form of Qi (life force energy) that maintains resistance against illness

In addition, in TCM there are many inter-relationships between the functions of Jing and those of the kidneys (where Jing is stored), the liver (where blood is stored) and the blood.

What happens when Jing starts to run out?

Your level of Jing naturally starts to decline from mid-life onwards, and in TCM lack of Jing is considered responsible for many of the signs of ageing, especially those associated with the physiological functions listed above.

The resulting signs and symptoms may include:

  • Stiffness (reduced elasticity) in the bones, joints and tendons, sometimes with weakness and mild aches and pains in the lower back and knees
  • Greying hair and hair loss
  • Reduced immune defences
  • Occasional memory problems, forgetfulness or dizziness
  • Hearing difficulties
  • Reduced sexual vitality and function
  • Menopausal symptoms like hot flushes
  • Increased susceptibility to minor infections, like common colds and flu

​Preserving Jing

From the perspective of TCM, conserving your Jing for as long as possible will enable you to enjoy good health in your old age.  

Your focus should be on leading a healthy, balanced lifestyle that incorporates habits that support your Jing and minimises those that deplete it. Here’s a quick summary to get you started:

  • Eat a nutritious, balanced diet. Remember, you top up your Jing with nutritive substances from the food and drink you consume
  • Get plenty of fresh air for the same reason
  • Exercise regularly – because if your body isn’t active, your Jing won’t be either. Forms of exercise considered especially beneficial for the preservation of Jing include tai chi and qigong
  • Maintain a healthy balance between work and rest. Being overworked, overly busy or stressed is considered highly detrimental to Jing in TCM
  • Be mindful of your sexual activity too. While sex is considered healthy and enjoyable in TCM, some of your Jing is transferred to your sexual partner during intercourse via the body fluids, so it may become depleted if you’re highly sexually active

Herbs traditionally used to strengthen Jing in TCM

kidney health and goji berries

Goji berries and rehmannia root are traditionally taken to strengthen and invigorate Jing in TCM, where they’re also traditionally used as tonics for the kidneys and liver.

Also consider dong quai, which is traditionally used to boost Jing by improving blood health in TCM, as well as to relieve menopausal symptoms like hot flushes.

Thanks to its actions as a blood tonic and for nourishing Jing, dong quai is also traditionally used to improve hair health in TCM.

And finally, consider schisandra, which is traditionally used to invigorate Jing and help the body adapt to stress in TCM. It’s often taken with horny goat weed, which is traditionally used to strengthen the kidneys to support healthy sexual function and to promote a healthy libido in TCM.

Always read the label. Follow the directions for use. If symptoms persist, worsen or change unexpectedly, talk to your health professional.
