Shi Jue Ming is the crushed shell of the abalone sea snail, used as a single drug in Traditional Chinese Medicine (TCM). It is not a plant and not a food. It is a mineral-type medicine, made mostly of calcium carbonate (chalk), and it is nearly always cooked into a herbal soup with other herbs rather than taken alone.
In TCM it is given for patterns described as "liver yang rising" and "liver fire": dizziness, headache, ringing in the ears, irritability, and red, sore or blurry eyes. Practitioners also use it for long-term poor night vision and for eye problems linked to heat in the body.
The honest evidence picture is simple. Shi Jue Ming has centuries of standing inside one tradition, but long traditional use is not the same thing as proof that it works, and that difference is not restated in every section below. No human trials of abalone shell on its own have been published that we could identify, so its modern evidence grade is insufficient.
Nobody has shown clearly how Shi Jue Ming works in the body, and that is the fair answer.
The shell is largely calcium carbonate, the same compound used in chalky antacid tablets. Once swallowed, it neutralises some stomach acid and raises the calcium and mineral load of the gut. That chemistry is well understood, but it does not obviously explain the eye and headache uses it is given for.
TCM explains it differently, in its own language: the shell is heavy and cooling, so it is said to "anchor" rising yang and settle the liver. That is a traditional model of the body, not a description of measured biology.
Laboratory and animal studies have looked at abalone shell powder and its protein layer for effects on blood pressure, liver enzymes and eye tissue. Those results are early, were not done in people, and should not be read as evidence that the herb does any of these things in you.
Shi Jue Ming reaches you in a few forms:
Raw crushed shell (sheng shi jue ming) — coarse fragments, cooked in water. This is the usual form for headache, dizziness and eye complaints.
Calcined shell (duan shi jue ming) — roasted until brittle, then crushed. Traditionally chosen when stomach acid or reflux is also present.
Fine powder — ground and taken in small amounts, sometimes stirred into liquid or pressed into pills.
Granule or concentrated extract — a dried water extract, dissolved in hot water. Convenient, though mineral herbs extract poorly into water in the first place.
In practice a practitioner almost always includes it in a multi-herb formula rather than giving it alone.
Shi Jue Ming has been in Chinese medical writing for roughly 1,500 years. It appears in the Ming Yi Bie Lu (Miscellaneous Records of Famous Physicians, around 500 CE) and is carried forward in later classics and in the modern Chinese Pharmacopoeia.
The name means "stone decided brightness", a reference to its long-standing use for the eyes. It is a staple of one tradition rather than a herb shared across many, and it remains a common ingredient in Chinese eye and headache formulas today.
See a doctor promptly if a headache is sudden and severe, comes with weakness, confusion or slurred speech, or is the worst you have had.
Get same-day eye care for sudden vision loss, sudden eye pain, flashes and floaters, or an eye injury. Do not wait to see whether a herb helps.
Book a routine appointment if ringing in one ear, hearing loss, ongoing dizziness or blurred vision lasts more than a couple of weeks, or if headaches keep coming back.
Stop the herb and seek medical help straight away if you get a rash, itching, swelling of the lips, face or throat, or trouble breathing. Also call your doctor if you feel unusually thirsty, confused, weak or nauseated on high doses, which can signal too much calcium in the blood.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Shi Jue Ming 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.
