White spots on the nails (clinically known as leukonychia) are a common symptom of injuries to the nail matrix or applied pressure. Leukonychia is a medical term derived from the Greek words leuko and onyx, which translates to white and nail, respectively.
Sometimes, they can be a sign of an underlying health condition. Be mindful that anyone can have the symptom, irrespective of age, gender, or ethnicity.

The Different Types of White Spots on the Nails
The appearance of nail spots can be categorised by pathology, distribution, and timeline of development.

Under the pathology umbrella category, the symptom’s onset can be broken down into true or apparent leukonychia. True leukonychia describes discolouration due to

A total or partial nail coverage may help you determine the reason behind the condition. Partial leukonychia can fall under three sub-types. These are:
- Punctate: Pen-point-sized dots
- Longitudinal: Lines running across the nails
- Striate: Singular dots or horizontal bands that are parallel to the nail base

Recessive inheritance is a common trait of congenital leukonychia. On the contrary, acquired leukonychia is the by-product of systemic disease.
What are the Primary Causes of White Spots on the Nails?
The most notable triggers of leukonychia are injuries or existing health conditions.
Body constitution weaknesses
A healthy circulation of Liver blood plays a pivotal role in maintaining nail and tendon health.
“Changes in nail appearance are usually indicative of a Blood Deficiency. A likely reason for this is fatigue, which may impair circulation to the Heart, Liver, and nail health,” explains Real Health Medical’s Chief Physician Chu I Ta.
Nail fungus (onychomycosis) is more prominent in toenails than fingernails and grows between the keratin layers in the nail. The condition will eventually produce brown or yellow-coloured nails but will first appear white at the tip of the nail. Toenails may appear flaky and become thick and brittle.
Trauma is often associated with punctate leukonychia. Slamming your finger in a car door (major trauma) may turn the entire nail white if it detaches from the nail bed. Likewise, habitual nail-biting (minor trauma) can provoke the appearance of white spots.
Trauma also relates to the use of chemical-based products, such as polishes and acrylic nails. Frequent manicures may also cause damage to the nail matrix.
Severe problems like diabetes, heart failure, and liver disease can be reflected through longitudinal leukonychia. Interestingly, longitudinal and striate leukonychia may also be side effects of chemotherapy. Heavy metal poisoning from arsenic can also cause lines to develop on nail plates.
Insufficient calcium, selenium, and zinc can make the nails appear as white-coloured bands or spots.
How Do You Get Rid of White Spots on the Nails?
A Blood Deficiency can be addressed with herbal remedies like Gui Pi Tang (归脾汤
- Blood Stasis: Xue Fu Zhu Yu soup (血府逐瘀汤) or Tao Hong Si Wu soup (桃红四物汤)

The clinical treatment of white nail spots rests on the causes of the symptom’s onset. A healthcare provider may choose to use several tests to obtain a diagnosis, such as:
- Mycology: the study of fungi in nail clippings
- Nail biopsy: the study of nail tissue
- Blood tests: to identify the presence of a systemic disease
Trauma-induced nail spots will naturally resolve on their own. You can manage true leukonychia by avoiding cuticle manipulation and limiting the use of abrasive nail care products. Fungal nail infections may be treated with antifungal medications.
Don’t be alarmed if you find white spots on your nails. Take comfort in knowing that both clinical and traditional medicine takes a holistic approach to alleviate the symptom. Ideally, speak to a licensed TCM practitioner before using herbal remedies to avoid potential contraindications.
