A Taiwan-based traditional Chinese medicine physician lays out the physical signals the body sends in advance, explains the underlying pathology through a TCM lens, and outlines the herbal formulas and lifestyle practices that can reduce the risk of a first or repeat episode. Stroke does not arrive without warning, and the conditions that cause it are identifiable and, in many cases, treatable before a crisis hits.
In the fast-paced modern world, where long work hours, chronic stress, and irregular eating habits are the norm, the conditions that cause stroke build silently for years: elevated blood lipids, arterial hardening, abnormal blood pressure. By the time any of these tips into crisis, the damage can be catastrophic. Limb paralysis, loss of movement on one side of the body, or death are all possible outcomes of a brain stroke that could, with proper attention, have been anticipated and prevented.
Anyone who frequently experiences chest tightness, dizziness, headaches, a tingling or numb scalp, blurred vision, sudden memory lapses, unexpected breaks in the flow of thought, or numbness in the hands and feet should take those symptoms seriously. Muscle twitching, trembling at the corners of the mouth, or an eyelid that flutters on its own are further warnings that demand attention.
How traditional Chinese medicine explains stroke risk
Traditional Chinese medicine (TCM) traces stroke to a condition known as “phlegm and blood stasis obstructing the channels” (痰瘀阻络, tán yū zǔ luò). The two terms carry specific clinical meanings.
“Phlegm,” in the TCM framework, refers to pathological metabolic byproducts that accumulate in the body, roughly equivalent to what people colloquially call “thick blood” or “dirty blood.” Elevated blood lipids are a textbook example of this kind of accumulation. Classical Chinese medical texts observed that “people of heavy build tend toward phlegm and dampness,” meaning that excess body weight, by TCM reasoning, creates an inherent vulnerability. Typical presentations include persistent fatigue, dizziness, chest tightness, stomach bloating, and a sensation of phlegm caught in the throat.

“Blood stasis” refers to impeded circulation, the colloquial image of blood that cannot flow freely through its pathways. Clinically it manifests as scalp or limb numbness, stabbing pains in the body, and a tongue that appears purplish or shows stasis spots. When phlegm and blood stasis combine to produce arterial hardening and elevated blood pressure, additional symptoms can appear: facial flushing, a heavy throbbing sensation in the head, insomnia, and vivid or disturbing dreams. TCM calls this “yang hyperactivity,” the body’s upward surging energy no longer held in check.
The herbal formulas used to clear blockages and restore circulation
For patients whose primary pattern is phlegm and blood stasis, the TCM therapeutic principle is to dispel stasis, clear the channels, dissolve phlegm, and drain turbidity. Two classic prescriptions are commonly deployed: Warm the Gallbladder Decoction (溫膽湯, Wen Dan Tang) and Drive Out Stasis from the Mansion of Blood Decoction (血府逐瘀湯, Xue Fu Zhu Yu Tang). Both are designed to improve blood fluidity and resolve the accumulation that TCM associates with pre-stroke conditions.
For patients who also exhibit yang hyperactivity, the treatment strategy shifts to nourishing the kidney’s yin energy to anchor the liver’s yang, calming the liver, subduing the rising yang, and simultaneously dissolving phlegm and extinguishing wind, a TCM term for the internal turbulence that can trigger acute neurological events. Three classic formulas serve this purpose: Sedate the Liver and Extinguish Wind Decoction (鎮肝熄風湯, Zhen Gan Xi Feng Tang), Enrich Water and Clear the Liver Drink (滋水清肝飲, Zi Shui Qing Gan Yin), and Gastrodia and Uncaria Beverage (天麻鉤藤飲, Tian Ma Gou Teng Yin). A trained TCM physician selects among them based on the patient’s individual presentation.
What modern research shows about ginkgo leaf
Ginkgo leaf (銀杏葉, Yin Xing Ye) contains flavonoid compounds that dilate the coronary and cerebral arteries, improve circulation to both the heart and brain, and lower serum cholesterol. These properties have made ginkgo a recognized treatment option for coronary heart disease and angina, hypertension, hyperlipidemia, and cerebrovascular spasm.
Clinicians have also applied it to tinnitus, vertigo, stroke, age-related memory decline, and general anti-aging protocols. For patients who have already had a stroke, or who show clear risk factors, ginkgo leaf preparations can help prevent further obstruction of cerebral blood flow and assist the body in clearing toxic byproducts from ischemic tissue.
Why stroke survivors face a heightened risk of a more severe second episode
The Qing dynasty physician Shen Jin’ao, one of the most influential medical writers of his era, observed: “When a wind disease has resolved but its root has not been fully eradicated, it will recur after one or two years, or perhaps several years, and when it recurs it will inevitably be more severe, sometimes fatally so.”
Stroke recurrence is common, and each subsequent episode tends to cause greater damage than the one before. Anyone who has suffered a stroke, or who carries significant risk factors, carries what the author describes as a ticking time bomb, one that careful daily health management can defuse but that neglect can detonate without warning. This means consistent regulation of diet, sleep, stress, and physical activity, alongside appropriate TCM treatment tailored to the individual pattern. The warning signs described above should be treated as urgent signals, responded to quickly rather than explained away.
