Lunula and Health: What Your Nails Reveal According to TCM in Singapore

Did you know your fingernails can reflect the state of your inner health? In Traditional Chinese Medicine (TCM), areas like the fingernails, hands, ears, and feet are known as external mirrors of internal organs. One of the most telling signs? The lunula—the white half-moon shape at the base of your nails.

In TCM Singapore practices, experienced physicians often check the appearance of your nails during consultation, because your lunula, colour, and texture can offer insights into your qi, blood, and organ health.

What Is the Lunula in TCM?

The lunula is the crescent-shaped white area at the base of your nail, usually visible on the thumbs and sometimes on the other fingers. In TCM, the lunula is seen as the boundary between yin and yang, a representation of your body’s essence and vitality. It’s also referred to as your “health circle.”

👉 A healthy person generally has visible lunula on 8 to 10 fingers (excluding the pinky). But that doesn’t mean the bigger the better!

What the Lunula Reveals About Your Body

Small or Faint Lunula

If the lunula is smaller than 1/5 of the nail or barely visible, it may suggest low energy levels, poor digestion, and weaker qi and blood. Many TCM Singapore doctors associate this with cold or deficient constitutions.

Large Lunula

A lunula covering more than 1/5 of the nail surface may indicate excessive heart fire, which could be linked to heart strain, high blood pressure, or even cardiovascular risks.

Suddenly Disappearing Lunula

If your lunula suddenly fades, becomes dull, or disappears, it might signal chronic fatigue or underlying conditions like inflammation, blood disorders, or severe nutrient depletion. It’s advisable to seek TCM consultation in Singapore for a holistic assessment.

Lunula and TCM Body Types

In TCM, body constitutions are typically classified into cold, hot, or mixed (yin-yang imbalance). Your lunula pattern can give clues:

❄️ Cold Constitution

Lunula is faint, dull, or absent
You may feel cold easily, lack energy, have digestive issues, or pale skin

TCM Tip: Eat warming foods like mutton, ginger, and coriander. Consider herbal formulas such as Jin Gui Shen Qi Wan to warm the kidney yang and promote circulation.

🔥 Heat Constitution

All ten fingers show large, clear lunula
You might often feel hot, get irritable, have dry mouth, or constipation

TCM Tip: Eat more cooling foods like bitter gourd and celery. TCM formulas like Liang Xue Si Wu Tang can help clear internal heat.

⚖️ Mixed or Yin-Yang Imbalance

Lunula appears blurry, unclear, or inconsistent across fingers
You may experience bloating, emotional swings, and fatigue

TCM Tip: Balanced herbal remedies such as Xiao Chai Hu Tang or Er Xian Tang are often prescribed in TCM Singapore clinics to regulate the imbalance.

What Nail Colour Says About Your Health

In TCM, healthy nails should be rosy pink with a natural shine. Changes in colour may indicate internal imbalances:

Pale nails: Could suggest blood deficiency (commonly seen in women).
Purple nails: May indicate poor circulation or heart-related issues.
Bluish nails: Often a sign of severe cold or blood stasis.
Yellow nails: Could be linked to liver, gallbladder, or blood sugar problems.
Blue-tinted nails: May reflect respiratory issues or lung congestion.

Nail Texture and Health Clues

Don’t ignore lines or changes on your nails—they may reveal early signs of stress or illness.

Vertical lines: If fine and recent, may be due to overwork or lack of sleep. Persistent vertical lines might indicate chronic internal imbalances.
Horizontal lines (Beau’s lines): Usually point to past illness or organ stress; they move upwards as the nail grows.
White spots: Often caused by mineral deficiencies (like calcium or zinc), or possible parasitic infections.
Yellow spots or cloudy areas: May indicate digestive system weaknesses.
Hangnails or peeling skin around nails: Often linked to vitamin deficiencies or dry heat.
