Introducing Tsumura Kampo No. 54 'Yokukansan', for those who feel high-strung due to stress, insomnia, irritability, or teeth grinding.

In Traditional Chinese Medicine, this herbal medicine is classified as
a 'He Gan Xi Feng Yao' (Liver-calming and wind-extinguishing medicine).

So, when should it be used?

This herbal medicine is used when:
1. The autonomic nervous system is overstimulated,

2. As a result of that overstimulation,

the brain's braking function is lost,

3. And symptoms such as insomnia, eyelid twitching,
dizziness, or an inability to forget unpleasant events are occurring.

Let me explain the ingredients.

Uncaria Hook (Chotoko):
Suppresses uncontrollable mental instability caused by the loss of the body's Yin (which acts as a brake on excitement).

Bupleurum Root (Saiko), Cnidium Rhizome (Senkyu):
Promote the circulation of Qi (the body's energy) that has become stagnant.

Angelica Root (Toki):
Improves blood circulation while increasing blood volume, repairing the brain's braking system by regulating stomach function.

Atractylodes Rhizome (Byakujutsu), Poria (Bukuryo), Licorice (Kanzo):
Regulate stomach function to increase blood volume
(since blood, which acts as the braking component, is produced from food).

It is composed of these ingredients.

As the name suggests, it is used for 'Kan no mushi' (infantile irritability), so it is also a herbal medicine that has been used for children's night crying.

A similarly named medicine,
Yokukansankachimpihange,
has almost the same effect.

This herbal medicine is unlikely to cause side effects even when used for a long time.

However, because it has the effect of lowering Qi, please avoid it if you suffer from dizziness, lightheadedness, gastroptosis, or diarrhea caused by a lack of rising Qi.


Since you cannot self-diagnose what it means for Qi not to rise,
please consult a professional.

To understand herbal medicine, it is important to know not just the name, but the contents.
Let's study it step by step together.
