This one is for the heavy head, the foggy morning, and the neck tension that travels with them.

Phlegm in Chinese medicine is broader than what you cough up. It is a whole pattern of heaviness.

Here’s what the formula actually is, why nearly everything in the phlegm category is built on it, and who it’s not for.

Quick Answer

Warm Hearth is Er Chen Er Zhu Tang — Er Chen Tang, the foundational damp-phlegm formula of Chinese herbal medicine, plus the two great damp-drying atractylodes herbs — made as a warm everyday tea. It is built for the heavy, congested, sluggish, coated damp-phlegm picture: the heavy head, the foggy morning, and the neck tension that travels with them. If you tend to run dry, this is probably not your formula; if you are pregnant or take prescription medication, check with your practitioner first.

What Warm Hearth Actually Is

Er Chen Tang — the Two-Aged Decoction — is the base formula for damp-phlegm in Chinese herbal medicine. Nearly every phlegm formula in the tradition is built on top of it.

It addresses the heavy, congested, sluggish, coated feeling that comes when the body accumulates thick fluid it cannot transform. Not a cough formula. A whole-system formula.

Warm Hearth is the classical modification Er Chen Er Zhu Tang — the base plus Bai Zhu and Cang Zhu, the two great damp-drying atractylodes herbs, for more drying and strengthening power.

Why This Is a Foundation Stone

Practitioners think of Er Chen Tang the way builders think of a footing. It rarely gets the credit, and almost everything sits on it.

Botanical Biohacking took that foundation and made it a warm, everyday tea — thirty teabags to a box — so damp-phlegm support becomes a daily ritual rather than a decoction to prepare.

How It's Sourced and Tested

The same protocol runs across the whole line.

  • Heavy metals — screened in every batch
  • Pesticide residue — screened in every batch
  • Microbial load — screened in every batch

Inside the Formula

The Er Chen core, plus the atractylodes pair.

The Er Chen Core

  • Chen Pi (aged tangerine peel) — moves qi, dries damp
  • Fa Ban Xia (prepared pinellia) — transforms phlegm, settles the stomach
  • Fu Ling (poria) — drains damp, supports the middle
  • Gan Cao (licorice) — harmonizes

The Atractylodes Reinforcement

  • Bai Zhu (white atractylodes) — strengthens the spleen, dries damp
  • Cang Zhu (grey atractylodes) — strongly dries damp, restores movement

Who This Is Not For

Warm Hearth is built for the damp-phlegm picture. If you tend to run dry, this is probably not your formula. If you are pregnant or take prescription medication, check with your practitioner before making any phlegm-drying formula a daily habit.

Formulas do not survive a thousand years of continuous clinical use by accident. Er Chen Tang is still the base that everything else gets built on. — Will Sheppy, L.Ac.

Sol Tea: For the Foggy, Heavy Head That Feels Waterlogged

Sometimes the head feels foggy because the body is waterlogged.

Sol Tea is built on Ling Gui Zhu Gan Tang — four herbs, two thousand years — written for the patient too depleted to tonify. Not enough heat to move fluid, so fluid pools and then rises.

Here’s what the formula actually is, why four herbs is the point, and what’s inside.

Quick Answer

Sol Tea is built on Ling Gui Zhu Gan Tang — Poria, Cinnamon Twig, Atractylodes and Licorice Decoction — one of the great phlegm-fluid formulas, in continuous use for roughly two thousand years. It was written for the heavy, dizzy, cotton-wool-head pattern where fluid pools because there isn’t enough warmth to move it, and for the patient who gets foggier when tonified. If head symptoms are new, severe, or worsening, get properly evaluated first — Sol is a fit for the right pattern, not a substitute for a diagnosis.

What Sol Tea Actually Is

Ling Gui Zhu Gan Tang — Poria, Cinnamon Twig, Atractylodes and Licorice Decoction — is one of the great phlegm-fluid formulas. It warms yang, strengthens the spleen’s handling of fluids, and transforms the thin, sloshing dampness that rises up to cloud the head.

That is the pattern behind the heavy, dizzy, cotton-wool feeling: not enough heat to move fluid, so fluid pools and then rises.

It is a small formula — only four herbs — but elegantly constructed, which is why it has stayed in constant use for roughly two thousand years and why so many later formulas are built on top of it.

Why Four Herbs Is the Point

There is a clinical situation this formula was made for: the patient who needs support but cannot tolerate being tonified. Rich, building formulas sit heavily on a system that is already damp, and the result is more fog, not less.

Sol works the other direction. It removes what is in the way first. Four of the safest, most-used herbs in the entire materia medica, doing one job cleanly.

How It's Sourced and Tested

The same protocol applies across the line — heavy metals, pesticide residue, and microbial load.

  • Heavy metals — screened in every batch
  • Pesticide residue — screened in every batch
  • Microbial load — screened in every batch

Inside the Formula

Four herbs, four clearly defined roles — classic monarch-to-envoy construction.

Warm and Drain

  • Fu Ling (poria) — drains damp and settles the middle
  • Gui Zhi (cinnamon twig) — warms yang, moves fluid, calms rising sensations

Strengthen and Harmonize

  • Bai Zhu (white atractylodes) — strengthens the spleen, dries damp
  • Gan Cao (honey-baked licorice) — harmonizes and supports the middle

Before You Start

Dizziness has many causes, and not all of them are the fluid pattern this formula addresses. If head symptoms are new, severe, or worsening, get properly evaluated first. Sol is a good fit for the right pattern — not a substitute for a diagnosis.

This is the formula for the person who gets worse when you try to build them up. Clear what is in the way first, and the building becomes possible. — Will Sheppy, L.Ac.

Neurogene Tea: For Numbness and Tingling in Hands and Feet

Table of Contents

Numbness and tingling are not always a nerve problem. Sometimes they are a delivery problem.

When circulation is too weak to reach the far end of a nerve, the sensation at the fingertips and toes is often the first thing to fade. Neurogene Tea was built for that picture — to support the pressure behind circulation rather than force it.

Here’s what the formula actually is, who formulates it, and what’s inside.

Quick Answer

Neurogene Tea is an Imperial-grade modification of Bu Yang Huan Wu Tang — the most-studied blood-moving formula in Chinese medicine — built for the picture where circulation is too weak to reach the far end of a nerve. A very large dose of Huang Qi (astragalus) supplies the push; a small team of blood-movers clears the path. It is a blood-moving formula: not used during pregnancy, and anyone on anticoagulants, with a bleeding disorder, or recovering from a stroke should talk with their physician and practitioner first.

What Neurogene Tea Actually Is

Neurogene is an Imperial-grade modification of Bu Yang Huan Wu Tang — Tonify the Yang to Restore Five-Tenths Decoction. In China it is the single most-used formula for post-stroke recovery, and it has been studied more than almost any other blood-moving prescription.

The classical logic is elegant. A very large dose of Huang Qi (astragalus) supplies the qi that pushes blood; a small team of blood-movers clears the obstruction that qi is pushing against. The formula does not force circulation. It restores the pressure behind it.

The modification adds herbs aimed at the neuro-inflammatory side of the picture — Tian Ma and Gou Teng to settle wind, Jin Yin Hua and Lian Qiao to clear heat, Da Huang to keep things moving downward.

Who Formulates This

Dr. Jin Zhao is the main formulator for Botanical Biohacking. He practices in Chengdu, sees up to 200 patients a day, and specializes in dampness. His approach was refined across tens of thousands of patients, working through the upper, middle, and lower jiao.

Pharmacology professor Dr. Zhong Shi Hong fine-tunes the formulas. Dr. Lan, PhD — Dr. Jin’s younger classmate — is the herbal pharmacologist who oversees testing and writes the practitioner letters.

A sourcing detail worth noting: this blend uses Qing Lian Qiao — unripe green forsythia — rather than the ripe fruit. It carries a higher concentration of forsythiaside. A small decision, made by someone paying attention.

How It's Sourced and Tested

Three categories of contamination matter for plant material from anywhere in the world: heavy metals, pesticide residue, and microbial load. Botanical Biohacking’s protocol addresses all three.

  • Heavy metals — screened in every batch
  • Pesticide residue — screened in every batch
  • Microbial load — screened in every batch

Inside the Formula

Eleven herbs, organized around one idea: supply the push, then clear the path.

Supply the Push

  • Huang Qi (astragalus) — the monarch herb, in a large dose

Move the Blood

  • Dang Gui (angelica) — nourishes and moves
  • Chuan Xiong (ligusticum) — moves blood and qi
  • Chi Shao (red peony) — cools and invigorates
  • Tao Ren (peach kernel) & Hong Hua (safflower) — the classical stasis-breaking pair

Settle and Clear

  • Tian Ma (gastrodia) & Gou Teng (uncaria) — settle internal wind
  • Jin Yin Hua (honeysuckle) & Qing Lian Qiao (green forsythia) — clear heat
  • Da Huang (rhubarb root) — keeps things moving downward

Before You Start

This is a blood-moving formula. It is not used during pregnancy. If you take anticoagulants, have a bleeding disorder, or are recovering from a stroke or any neurological event, this belongs in a conversation with your physician and practitioner — not in a self-directed experiment.

Numbness at the fingertips and toes is often the last stop on a long supply line. When you improve what reaches the end of that line, the sensation frequently follows. — Will Sheppy, L.Ac.

It was written for the picture where circulation is too weak to reach the far end of a nerve — numbness and tingling at the fingertips and toes that behaves less like a nerve problem and more like a delivery problem.

No — this is a blood-moving formula and it is not used during pregnancy. If you take anticoagulants, have a bleeding disorder, or are recovering from a stroke or any neurological event, this belongs in a conversation with your physician and practitioner, not a self-directed experiment.
