From the practitioner letters
The months after a stroke are their own clinical season — and Chinese medicine wrote a formula for exactly that window.

Dr. Xuelan Qiu — “Dr. Lan” — Botanical Biohacking
There is a patient every acupuncturist eventually meets: the hospital did its work, the clot was caught — and she still has not come back. This month’s letter from Dr. Lan is about that patient, and about Bu Yang Huan Wu Tang, the two-hundred-year-old formula Chinese medicine built for the months after a stroke. Dr. Xuelan Qiu — Dr. Lan — is the pharmacist behind the Botanical Biohacking formulas on the Chorus shelf and in my clinic; she writes to practitioners most weeks. This one made me stop, because it names something families see long before charts do.
The short version
Bu Yang Huan Wu Tang is the classical formula for the pattern Chinese medicine calls qi deficiency with blood stasis — the deep fatigue, slowed limb, and slowed word-finding that can linger in the months after a stroke. Botanical Biohacking’s Neurogene Tea is a modern modification of it. It supports the body’s own recovery work; it does not treat or cure stroke, and it belongs alongside your physician’s care, never in place of it.
What Dr. Lan described
Her letter opens three months after the event. The hospital has discharged the patient. Nothing on the follow-up scan is getting worse. And yet:
“The fatigue is the kind sleep does not touch. The right hand is slower than the left. The word she wants takes a moment longer to arrive. Her family is patient, and watching.”
— Dr. Lan, Botanical Biohacking practitioner letter, August 2026
Western follow-up care is superb at preventing the next stroke. It has less to offer the slow middle — the season where the emergency is over but the person is not yet back. Dr. Lan’s point: Chinese medicine has always treated that season as its own condition, with its own name and formula.
The pattern behind it
The classical name is qi xu xue yu — qi deficiency with blood stasis. In patient language: the body’s pushing force has collapsed, so blood no longer moves briskly into the small vessels, and where it doesn’t move, function fades. Wang Qing-Ren named the pattern in his 1830 text the Yi Lin Gai Cuo, and wrote a single formula for it. If you have read my note on the Xiao Yao San pattern on the clinic blog, this is its opposite pole — that one is about qi that is stuck; this one is about qi that is spent.
What the pattern looks like
- Fatigue that sleep does not repay. Rest happens; recovery doesn’t.
- One side lags. A hand, a leg, a corner of the face — slower rather than absent.
- Words arrive late. The thought is intact; the delivery hesitates.
- A pale tongue and a weak pulse. The signs we read in clinic that say the push is gone, not blocked.
When it is not this
New weakness, new confusion, a sudden worst-ever headache, new trouble speaking or seeing — those are emergency signs, not a pattern to brew tea for. Call 911. And any change in a post-stroke plan, herbal or otherwise, goes through the neurologist and the prescribing physician first.
The formula — Bu Yang Huan Wu Tang
The name translates roughly as “supplement the yang to restore the five-tenths” — Wang Qing-Ren’s image of a person operating at half their qi. The logic is elegant: one herb supplies the push, a small team clears the path.
- Huang Qi (astragalus) — the monarch herb, in a deliberately large dose, to restore the pressure behind circulation.
- Dang Gui, Chuan Xiong, Chi Shao — nourish and move the blood the qi is meant to push.
- Tao Ren and Hong Hua — the classical stasis-breaking pair, clearing the fine vessels.
Neurogene Tea is this base, modified for the patient Dr. Lan actually sees today. Gastrodia (Tian Ma) and uncaria (Gou Teng) are added to settle the internal wind that can persist after the event; honeysuckle (Jin Yin Hua) and green forsythia (Lian Qiao) address the lingering heat — the inflammatory layer. As she puts it:
“The base formula does the qi-and-blood work Wang Qing-Ren described. The additions speak to what the modern patient brings into the room.”
— Dr. Lan, August 2026
I wrote a fuller herb-by-herb breakdown of Neurogene Tea on the clinic blog, including the sourcing detail I like most — the blend uses unripe green forsythia, which carries a higher concentration of forsythiaside than the autumn fruit. A small decision, made by someone paying attention.
What I see in clinic
A rule I come back to constantly with post-stroke patients: move the excess before you tonify. Many present tight and held — an excess picture on the surface — and that stagnation is often covering deficiency underneath. Tonifying first feeds something that has nowhere to go. Once the excess has moved, if what’s in front of me is deficiency, Neurogene is the more tonifying choice on this shelf — the build-the-push formula, where Purple Star is the unclench formula.
On the needle side, I don’t reach for the textbook Four Gates with neurological presentations. My preferred trio is PC 6 with LR 5 to open the Jue Yin collaterals, and SP 6 to nourish underneath — PC 6 stimulates the median nerve, helps relax the curled-in tension of the yin channels, and is simply a good neurological point.
[WILL: add a line about the last patient you’d describe as “recovered from the event but not back to herself” — age range and what they came in for, no names]
[WILL: what do you tell people the first month on Neurogene feels like — what changes first, and what shouldn’t they expect?]
[WILL: your take on this letter — what do you agree with most, and where would you push back or add (points, Evil Bone Water, foot soak, lifestyle)?]
If you want the wider context for how these formulas are built and tested, I keep a practitioner’s guide to the whole Botanical Biohacking line on the clinic site.
What the research adds
Dr. Lan’s letter cites a 2025 study from a Hunan research group, and it checks out — with one caveat her letter doesn’t make loudly enough for my taste. Li and colleagues, in Phytomedicine, showed Bu Yang Huan Wu Tang protecting brain tissue after ischemia by quieting the complement and coagulation cascades — the two ancient alarm systems Dr. Lan describes — while repairing the blood–brain barrier and reducing the abnormal “pruning” of synapses that should have been left intact.1 The caveat: the striking damage numbers she quotes, including the comparison with a standard drug, come from that study’s rat model. Animal findings map a mechanism; they are not a promise about human outcomes.
The human evidence is broader but messier. A 2022 systematic review of 39 randomized trials in the stroke recovery period — exactly this letter’s window — found that adding the formula to conventional care improved neurological scores and daily-living function without adding adverse events, while calling for better trials.2 An earlier meta-analysis reached a similar cautious conclusion in acute stroke,3 and a review of 56 animal studies found consistent neuroprotection.4 Honest summary: two hundred years of clinical use, an increasingly well-mapped mechanism, supportive but imperfect human trials.
How Dr. Lan recommends using it
Her protocol is specific: for the post-stroke patient, two bags daily for the first month, then one bag daily for months two and three, with cognitive and motor function re-evaluated at the three-month mark. “Patients often feel the change before they can describe it,” she writes. She also pairs it with daily Microgard, her gut-brain ground formula, which Chorus does not currently carry — the gut-brain groundwork idea will be familiar to anyone in the Gut Brain Synchrony community.
My additions before anyone starts: this is a blood-moving formula. It is not used during pregnancy. If you take anticoagulants or antiplatelet drugs, have a bleeding disorder, or are recovering from a stroke or any neurological event, this belongs in a conversation with your physician and your practitioner — not in a self-directed experiment. Nothing here replaces your rehabilitation plan, your medications, or your follow-up imaging. Care continues alongside.

Questions people ask
What is Bu Yang Huan Wu Tang?
A classical Chinese formula written by Wang Qing-Ren in 1830 for qi deficiency with blood stasis — the pattern of deep fatigue and one-sided slowness seen in the months after a stroke. A large dose of astragalus supplies the qi; a team of blood-moving herbs clears the path. Neurogene Tea is a modern modification of it.
Can herbs help with recovery after a stroke?
Traditionally, this formula has been used to support the body during the weeks and months after the event — never the emergency itself. Human trials of Bu Yang Huan Wu Tang added to conventional care are encouraging but imperfect. Any herbal support belongs alongside your medical team’s rehabilitation plan, with their knowledge.
Who should not take Neurogene Tea?
It is not used during pregnancy, and anyone on anticoagulants or antiplatelet drugs, with a bleeding disorder, or recovering from a stroke or other neurological event should involve their physician and practitioner before starting — this is a blood-moving formula.
How is it taken?
In Dr. Lan’s protocol: two tea bags daily for the first month, then one daily for months two and three, with cognitive and motor function re-checked at the three-month mark by your practitioner.
