Quick Answer
ST40 Fenglong, often remembered as Abundant Bulge, is a Stomach meridian point on the outer lower leg. It appears in digestion and phlegm-related traditional language, but that vocabulary is not a modern medical label or result promise. Shin injury, swelling, varicose-vein concern, numbness, bruising, or severe pain should stop pressure.
Safety Decision
Stop before pressure if the body area is injured, the symptom is severe or unusual, or qualified care should come first.
Continue only as a short, comfortable, education-only routine after reading the locator and stop signs.
ST40 FenglongBefore You Try This
This ST40 page is educational and not medical advice. It cannot assess digestive symptoms, respiratory symptoms, leg swelling, bruising, injury, numbness, or whether pressure is suitable.
Ask qualified care for severe or persistent digestive symptoms, breathing symptoms, leg swelling, varicose-vein or clot concerns, injury, numbness, severe pain, medication questions, pregnancy, children, or chronic illness.
reader path
Is This the Right Page to Read Now?
This acupoint page fails if the Abundant Bulge on the outer lower leg in the Stomach family locator becomes a treatment shortcut, a stronger-pressure target, or a replacement for the named safety stop signs.
Read ST36 or the digestion guide first for mild meal context, then compare ST40 only if leg and symptom safety remain clear. Then choose read-only, one brief comfortable contact, a printable card, or a safety stop.
Diagram Notes
The marker highlights ST40 Fenglong, Abundant Bulge, on a outer lower leg locator view; its landmark cue is "On the outer lower leg along the muscle beside the shin, below ST36." Use it with the safety cues rather than treating the marker as clinical precision.
Locator overlay for ST40 Fenglong, Abundant Bulge, placed on CC BY 4.0 Servier Medical Art human anatomy base images and paired with a regional landmark view.
How to read the ST40 locator
- Start with the broad area: outer lower leg.
- Compare the written landmark: On the outer lower leg along the muscle beside the shin, below ST36.
- Use the marker as orientation, then let comfort and the avoid bruised or inflamed shin areas caution decide whether to stop.
The Abundant Bulge locator uses a licensed educational anatomy base for the outer lower leg; it is not a clinical locator or personal safety clearance.
Why This Page Gets Extra Attention
Reader Scenario
A reader arrives at ST40 after seeing a short chart and needs to verify the Abundant Bulge landmark on the outer lower leg before doing anything physical.
Common Misread
Do not use ST40 as a digestion and phlegm-related traditional language shortcut; the locator and caution still decide whether this stays reading-only.
Editorial Call
Abundant Bulge earns its length only when it separates outer lower leg touch, landmark confidence, digestion and phlegm-related traditional language context, and the reason to stop.
Best Next Choice
Choose whether Abundant Bulge should stay read-only, allow one brief comfortable outer lower leg contact, move to the printable card, or open a safety page.
Use the Abundant Bulge locator as a neighborhood check for the outer lower leg; the written landmark still outranks the marker.
ST40 Fenglong and the Abundant Bulge name
ST40 is the standard code for Fenglong, often translated as Abundant Bulge. The name helps readers remember an outer-lower-leg point in the Stomach meridian family. It does not make the page a digestive, respiratory, weight, or phlegm answer.
Traditional phlegm language needs careful reading
Some traditional sources connect ST40 with phlegm vocabulary. On this site, that word is treated as cultural and historical language, not a modern medical label. A reader should not use ST40 to interpret mucus, coughing, digestion, metabolism, or any personal symptom.
Lower-leg safety comes before point comparison
Bruising, shin injury, swelling, numbness, varicose-vein concern, clot concern, infection signs, severe pain, or unexplained leg symptoms should stop pressure. A Stomach meridian label does not make lower-leg tissue risk disappear.
How ST40 relates to ST36 and ST25
ST36 is the first lower-leg digestion-context page. ST25 is an abdomen point with stricter abdominal safety. ST40 can be a secondary comparison when the reader is learning Stomach meridian vocabulary. It is not an upgrade from ST36 or a substitute for abdominal safety.
The wrong way to read ST40
The wrong reading is: because ST40 is linked with phlegm language, it belongs whenever breathing, mucus, digestion, or weight words appear. A safer reading is: ST40 is a named lower-leg point, and the old vocabulary needs translation before any practical page is chosen.
Technique boundaries for ST40
This page does not teach acupuncture, moxa, cupping, scraping, pressure dosing, digestive care, breathing care, or weight-loss routines. It keeps Stomach meridian vocabulary, leg location, and safety links separate.
Best next page after ST40
Choose ST36 for a first lower-leg digestion page, the digestion guide for mild meal context, or the Stomach meridian page for map language. Choose Safety or qualified care when symptoms are severe, persistent, respiratory, abdominal, leg-related, or unclear.
Full-page decision frame for ST40
ST40 Fenglong, Abundant Bulge, deserves more than a chart label because the reader has to make several separate decisions before touching the outer lower leg. The first decision is identity: this is a Stomach point, not a general label for every nearby tender place. The second decision is context: digestion and phlegm-related traditional language is a traditional or wellness reading cue, not a promise that pressure changes a personal condition. The third decision is safety: avoid bruised or inflamed shin areas. A full page for Abundant Bulge therefore has to slow the reader down. It names the point, describes the broad locator, explains why the point appears with certain routines, separates acupressure from professional techniques, and gives a conservative next page. If the reader only wants a quick answer, the safest quick answer is still narrow: read the locator, check the stop signs, and use the point only as education unless the situation is mild and comfortable.
How to verify the outer lower leg landmark
ST40 starts with the outer lower leg view, but the visual marker is only a region finder. The written landmark carries the real work: On the outer lower leg along the muscle beside the shin, below ST36. Use broad pressure and avoid bruised or inflamed shin areas. This matters for Abundant Bulge because readers often arrive after seeing a short social post, wrist band, point chart, or routine list. A chart can make the target look cleaner than a real body feels. The reader should first name the broad body area, then compare the landmark with bones, tendons, folds, or soft tissue nearby, then check whether the skin and sensation are normal. If the reader cannot repeat the landmark in plain English, ST40 should remain a reading page. If the body area is painful, numb, swollen, bruised, hot, wounded, recently injured, or hard to interpret, the locator has already done its job by telling the reader to stop.
What digestion and phlegm-related traditional language means on this page
The phrase digestion and phlegm-related traditional language explains why ST40 appears in this atlas, but it does not turn Abundant Bulge into a personal answer. For Fenglong, the use context is a signpost for reading related pages, not a guarantee, not a ranking, and not a reason to ignore symptoms. A better way to read the phrase is: people commonly encounter this point while researching digestion and phlegm-related traditional language, so the page should explain the name, locator, safety limits, and nearby choices clearly. That is very different from saying the point handles the concern. If the concern is mild and ordinary, ST40 can be part of a conservative reading path. If the concern is severe, new, persistent, frightening, pregnancy-related, medication-related, child-related, post-surgery, or connected with chronic illness, the digestion and phlegm-related traditional language phrase becomes less important than the safety path.
How ST40 relates to nearby point pages
Abundant Bulge should be compared with related pages only one relationship at a time. Useful comparison points include ST36 Zusanli (front outer lower leg), ST25 Tianshu (abdomen), SP6 Sanyinjiao (inner lower leg), BL40 Weizhong (back of knee). The relationship may come from the same meridian, the same body region, a similar routine page, or a shared beginner question, but those relationships do not make the points interchangeable. ST36 Zusanli has its own locator and caution; ST25 Tianshu has another. For ST40, the right comparison question is not "which point is stronger?" but "which page answers my current job?" A culture page explains the name. A printable page preserves memory. A wellness page compares a mild scenario. A safety page interrupts action. Reading those pages in the right order keeps Fenglong from becoming one more item in a long, unfocused list.
When pairing ST40 with another point makes sense
Pairing ST40 with another point is a reading decision before it is a physical routine. The safest pairing starts on a guide such as Acupressure for Digestion and Bloating, where the page can explain why several points appear together and which stop sign controls the whole set. For Abundant Bulge, pairing is most useful when it clarifies roles: one point may be the main locator to read, another may be a comparison point, and another may be a reason to leave the routine for Safety. Pairing is not useful when it simply adds more body areas because more points sound more complete. Each added point adds a new landmark, new tissue, and a new way to misread discomfort. If the reader cannot explain why ST40 belongs with the next point, the better step is to read one full page and stop.
Using ST40 inside a short routine
Abundant Bulge may appear in a mild self-care reading path, but the routine has to stay education-first and stop-first. A short routine around ST40 should have a beginning, a check, and an end. The beginning is the safety review: avoid bruised or inflamed shin areas. The check is the locator review: On the outer lower leg along the muscle beside the shin, below ST36. The end is a conscious decision to stop, continue reading, or open a related page. If gentle contact is appropriate, it should stay brief, comfortable, and easy to release. The reader should not chase a deep ache, try to create sensation, or keep pressing because a point name sounds important. A routine also should not stack ST40 with every point on the Stomach line. The page works best when it turns a vague impulse into one narrow action: read, locate broadly, touch lightly only if low risk is clear, and stop if the body gives any reason to stop.
Acupuncture, moxa, and cupping boundaries for ST40
ST40 can appear in professional acupuncture, moxibustion, or cupping contexts, but this page does not teach those methods. Acupuncture involves needles and belongs with qualified professional practice. Moxibustion involves heat, smoke, fire, burn risk, and pregnancy caution. Cupping involves suction, bruising, skin status, blood-thinner concerns, and injury questions. Those techniques are not stronger home versions of acupressure. For Abundant Bulge, the public page can explain that the same named point may appear across modalities, but it cannot convert professional technique language into instructions. If a reader came here searching for needling effects, moxa application, cupping placement, or stronger results, the safe answer is to stay in education mode and use qualified care or a licensed practitioner rather than improvising on the outer lower leg.
Wrong turns readers make with Abundant Bulge
A frequent wrong turn is to treat tenderness near ST40 as proof that the point was found. Tenderness can mean pressure is too strong, the tissue is irritated, or the wrong body area is being tested. Another wrong turn is to use digestion and phlegm-related traditional language as a shortcut around safety. A third is to keep moving across the outer lower leg until something feels intense. For Abundant Bulge, intensity is not the goal. Clarity is the goal. The reader should be able to say: this is the Stomach point Fenglong, the locator is On the outer lower leg along the muscle beside the shin, below ST36., the caution is avoid bruised or inflamed shin areas, and my next step is either read-only, gentle and brief, a related page, or qualified help. If that sentence cannot be said honestly, the page has not cleared pressure.
When ST40 is not the right next page
ST40 is not the right next page when the reader is trying to decide whether a symptom is serious, whether medicine can be changed, whether pregnancy or child use is safe, or whether an injury can be worked around. It is also not the right page when leg swelling, varicose veins, clot concern, bruising, numbness, or injury are present. In those cases, opening more point pages can create false momentum. The better route is a safety page, a professional conversation, or emergency guidance when warning signs are present. The value of the Abundant Bulge article remains intact even when the answer is not to press. It still gives language, location context, visual orientation, and relationships. A high-quality point page is allowed to say that the most useful next action is leaving the point page.
How the printable card should depend on this page
The printable ST40 card should be treated as a reminder after this full article, not as the article itself. A card can remember Fenglong, Abundant Bulge, the broad outer lower leg cue, and the stop signs, but it cannot carry the full context around digestion and phlegm-related traditional language, related points, source limits, or technique boundaries. For ST40, the card is useful when the reader has already read the landmark and wants a small memory aid. It is not useful when separated from the safety note, used during a high-risk situation, or shared as a quick instruction. If a card and the full page disagree in the reader's mind, the full page wins. If the card makes the action feel too easy, return to the full page or Safety.
Source and visual notes for Abundant Bulge
The source notes on ST40 have different jobs. Nomenclature and location sources keep ST40 Fenglong aligned with standard naming and broad locator language. Safety and health-information sources keep the page from becoming personal advice. The visual source identifies the licensed anatomy base used for orientation; it does not prove exact placement on any reader's body. For Abundant Bulge, that split is important because source lists can look more authoritative than they are. A source can support a name, a boundary, a cultural context, or a visual credit, but it cannot inspect the reader, confirm a symptom, clear an injury, or promise that digestion and phlegm-related traditional language will improve. The trustworthy reading is modest, traceable, and limited.
Final choice after reading ST40
End the Abundant Bulge page with one of four choices. Choice one is read-only: the reader understands ST40 better but does not touch the outer lower leg. Choice two is a brief gentle contact: the situation is mild, the skin and tissue feel normal, the landmark is clear, and the reader can release immediately. Choice three is a related page: the reader needs Acupressure for Digestion and Bloating, a name-meaning page, a printable memory aid, or a safety answer before acting. Choice four is qualified care: the concern is personal, severe, persistent, unusual, pregnancy-related, medication-related, child-related, chronic-condition-related, injury-related, or unclear. The page is successful when the reader can choose among those outcomes without relying on a chart alone. ST40 is a named point, but the decision is the real product.
Relationship map after ST40
ST40 should leave the reader with a relationship map, not just a locator. Start with the point itself: Fenglong, translated here as Abundant Bulge, sits in the Stomach context and uses the outer lower leg cue. Then compare neighboring reading paths: ST36 Zusanli on the front outer lower leg; ST25 Tianshu on the abdomen; SP6 Sanyinjiao on the inner lower leg; BL40 Weizhong on the back of knee; SP10 Xuehai on the inner thigh above knee. Those pages are not backup targets to press if ST40 feels uncertain; they are separate articles with separate body areas, cautions, and purposes. The broader use-case map is Acupressure for Digestion and Bloating. Use those pages only when the concern is mild enough to remain in education and safety navigation. This map is important because many people search for a point by discomfort, then keep adding pages until something feels persuasive. A better habit is to ask which relationship explains the next decision. If the next decision is name meaning, open Culture. If it is a memory aid, open Printable. If it is a combination, open the matching wellness guide. If it is risk, leave ST40 for Safety. The map keeps Abundant Bulge from becoming a loose claim about digestion and phlegm-related traditional language.
What the reader can safely take away from ST40
A careful takeaway from ST40 has five parts. First, remember the identity: ST40 Fenglong, Abundant Bulge, is a named point, not a universal body button. Second, remember the place: On the outer lower leg along the muscle beside the shin, below ST36. Third, remember the caution: avoid bruised or inflamed shin areas. Fourth, remember the use-language limit: digestion and phlegm-related traditional language explains why the point appears in traditional and wellness reading paths, but it cannot decide a personal symptom or promise an outcome. Fifth, remember the next action: read only, use a brief gentle contact only when low-risk context is obvious, compare one related page, or ask qualified care. This takeaway is intentionally practical. It gives the reader something to do with the page without turning the page into medical advice. For Abundant Bulge, the best result is not that the reader presses more confidently. The best result is that the reader can explain why this point fits, why it does not fit, or why the question belongs outside the atlas today.
What sources support beside the evidence note for ST40
Reader use: for ST40 Fenglong, the recalled sources support the exact article identity at /acupoints/st40-fenglong/, the displayed point name, and the broad locator language used on this page rather than a generic chart. Reader use: for ST40 Fenglong, the named sources support the page-specific boundary "This ST40 page is educational and not medical advice. It cannot assess digestive symptoms, respiratory symptoms, leg..." and the article value "A lower-leg point article that explains traditional phlegm/digestion vocabulary without making digestive or respirato..." without promising a result. Read these notes as traceability for this one point page; they cannot inspect the reader's skin, medication, pregnancy status, chronic illness, pain pattern, urgency, or whether pressure belongs today.
Questions Readers Usually Ask
What does phlegm mean on an ST40 page?
Here it is traditional vocabulary, not a modern medical label or a reason to press for mucus, cough, digestion, or weight concerns.
Should I read ST36 or ST40 first for digestion?
Read ST36 first. ST40 is a secondary Stomach meridian vocabulary page, not a stronger digestion point.
Can I press ST40 if my shin is bruised?
No. Bruising, swelling, injury, numbness, varicose-vein concern, clot concern, or severe pain should stop pressure.
