Fo Shou is the dried fruit of Buddha's hand, a citrus that grows in long yellow fingers. Chinese medicine uses it on its own to ease a tight chest, a full stomach and poor appetite. It is also used for a cough that brings up phlegm (thick mucus).
The proof is thin. We found no human trials that test Fo Shou by itself for any health problem. Long use in a tradition is not the same as proof that it works, so treat the claims below as unproven.
The fruit is sour and bitter and smells strongly of flowers. Cooks use the peel in tea, candy and jam. Many homes in China keep one just for the smell.
In the clinic it is given as a mild herb for the stomach and chest. It is usually one part of a larger formula rather than a stand-alone cure. Doctors in China often pair it with other herbs for bloating, burping and stress-linked stomach pain.
Because it is a citrus peel, it carries the same drug-interaction question that grapefruit does. That matters more than any side effect of the herb itself, so read the drug list further down before you start.
Nobody has shown how Fo Shou works in people. What follows is theory and lab work.
In Chinese medicine, Fo Shou is said to move stuck qi (the body's vital energy). Old texts say it calms the liver, settles the stomach and breaks up phlegm. That is a way of sorting symptoms, not a test of body chemistry.
Lab work points to the peel's oil and its flavonoids (plant colour compounds). In test dishes and in animals, these can relax gut muscle and calm swelling. No one has shown that this happens in your gut after a cup of the tea.
Fo Shou is sold most often as dried slices of the whole fruit. You simmer these in water to make a decoction (a strong herbal tea).
Other forms include tea bags, powder, candied peel and liquid extracts. Herb shops also sell it inside mixed Chinese formulas.
The essential oil is made for scent only. Do not swallow it.
Buddha's hand has been grown in China for well over a thousand years. Li Shizhen listed it in his great herbal book of 1596.
It became a staple stomach and chest herb in Chinese medicine and is still used that way. It is also a New Year gift fruit, kept in the house for luck and for its scent.
See a doctor if bloating, belly pain or a cough lasts more than two weeks, or gets worse. Go sooner if you lose weight without trying, vomit blood, pass black stools, have trouble swallowing, or have chest pain. Get urgent help if you get a rash, swollen lips or face, or trouble breathing after taking it. Tell your doctor or pharmacist you are taking it if you are on any prescription medicine.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Fo Shou is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
