A traditional Chinese medicine expert has revealed what your nails say about your health - down to each and every marking. 

The Eastern Philosophy, an Asian-owned small business that specializes in herbal medicine, frequently shares educational videos about health on TikTok, including one video on how to spot your health conditions just by looking at your nails. 

The now viral video has racked up nearly 400,000 views and shares how the small business's followers can spot any health concerns and decide if they need to see a doctor. 

'What your nails say about your health according to the Daoism tradition of body reading,' the video is captioned. 

In the video the Asian-owned small business reveals that if your nails curve downwards, it could indicate breathing problems. 

These types of nails are also known as clubbed nails and could be the first sign of a serious health concern. 

Nails that curl downwards could indicate you are suffering from breathing problems. 

Common health problems in those with downward curved nails include, chronic obstructive pulmonary (COPD), chronic bronchitis, asthma or even lung cancer. 

The nail bed usually begins by softening before curving.
