Materia medica
Herbarium
Cross-walked monographs: Chinese nature and flavor, Ayurvedic rasa and virya, Western tissue states, and a safety level that can refuse the plant. Kitchen spices sit beside poisons so the sieve is visible.
53 plants
Ginger
Zingiber officinale
The rare plant that almost every tradition kept. Fresh ginger is dispersing and anti-emetic; dried ginger is hotter and more interior. A teacher of the difference between a surface chill and a deep cold.
Turmeric
Curcuma longa
Ayurveda's gold standard for rakta and medas; TCM's jiang huang moves blood and qi in the shoulders. Food is the honest form. Isolated curcumin is a different, more aggressive object.
Ashwagandha
Withania somnifera
The horse-smell root: Ayurveda's rasayana for depleted vata, sleep, and reproductive reserve. Not a stimulant ginseng analogue. Night medicine, not a pre-workout.
Holy basil (Tulsi)
Ocimum tenuiflorum
The household rasayana of India. Aromatic, sattvic, and a daily tea more than a heroic cure.
Brahmi
Bacopa monnieri
Medhya rasayana — a mind tonic of slow, cumulative use. Not caffeine. Gotu kola is often also sold as brahmi; they are different plants.
Gotu kola
Centella asiatica
A cooling connective-tissue and mind herb that sits in both Ayurveda and southern Chinese folk use.
Licorice
Glycyrrhiza glabra / G. uralensis
The great harmonizer of Chinese formulas and the demulcent of Greco-Arabic and Ayurvedic throat medicine. Also a blood-pressure teacher: deglycyrrhizinated (DGL) is not the same as whole root.
Cinnamon
Cinnamomum cassia / C. verum
Cassia bark (rou gui) warms the Ming-men fire; cinnamon twig (gui zhi) walks the surface. True cinnamon (C. verum) is gentler and lower in coumarin.
Astragalus
Astragalus mongholicus
The great surface-qi tonic. Builds wei qi over weeks. Not for a fever you already have.
Schisandra
Schisandra chinensis
Five flavors in one berry: astringe jing, calm shen, moisten lung, and remember that sour holds what is leaking.
Goji
Lycium barbarum
A food-tonic for liver blood and kidney yin. Eyes and nights. Sweet, not a superfood stunt.
Reishi
Ganoderma lucidum / G. sichuanense
The spirit mushroom of the classics: calm shen, nourish heart qi. Bitter, slow, and not a latte flavoring.
Asian ginseng
Panax ginseng
A true qi tonic of collapse and emptiness — not a Tuesday afternoon pick-me-up. Red and white are different medicines. American ginseng (P. quinquefolius) is cooler.
Dong quai
Angelica sinensis
The blood-moving, blood-nourishing root of gynecologic tradition. Not 'female ginseng', and not a monthly self-experiment.
Mint / field mint
Mentha haplocalyx / M. spicata / M. piperita
Bo he vents wind-heat and soothes liver qi; peppermint is the Western carminative of stuck guts and tense brows.
Chamomile
Matricaria chamomilla
The gentle bitter of European and Unani pharmacies. Children, guts, and tempers. A tissue-state herb of irritation with tension.
Lemon balm
Melissa officinalis
Avicenna's heart herb. Lifts the spirits without caffeine and cools a fluttery chest.
Passionflower
Passiflora incarnata
A circular-thought nervine of the Americas. For the mind that will not stop arranging the furniture.
Milky oats / oatstraw
Avena sativa
The trophorestorative of a frayed nervous system. Food-like, slow, and almost never the wrong first move.
Nettle
Urtica dioica
Mineral green. Leaf as nutritive and mild alterative; root is a different prostate-adjacent medicine.
Dandelion
Taraxacum officinale
Leaf is a potassium-sparing bitter diuretic of folklore; root is a hepatic bitter. Pu gong ying clears heat-toxin in TCM.
Milk thistle
Silybum marianum
Mediterranean hepatic seed. Silymarin extracts are a modern concentrated form — still not a license to drink harder.
Hawthorn
Crataegus monogyna / C. laevigata
Europe's heart trophorestorative; Chinese shan zha is more a greasy-food digestive that also moves blood. Related, not identical.
Elder
Sambucus nigra
Flower for fevers that need to vent; berry as cooked food-medicine of winter. Raw berries are not a snack.
Echinacea
Echinacea angustifolia / E. purpurea
A specific of the Eclectics for septic, dull, and decaying tissue states — not a daily 'immune boost' candy.
Valerian
Valeriana officinalis
A heavy hypnotic that helps some and agitates others. If it makes you angry, you are in the other group.
Lavender
Lavandula angustifolia
Cooling aromatic of the nervous system. Tea and scent first; essential oil internally is not folk tea.
Rosemary
Salvia rosmarinus
A circulatory aromatic of memory and cold stagnation. Culinary first.
Thyme
Thymus vulgaris
A pungent antimicrobial aromatic of the respiratory mucosa. Kitchen steam is still medicine.
Fennel
Foeniculum vulgare
The after-meal seed of India and the Greco-Arabic world. Warms and moves a cramped gut without ginger's fire.
Cardamom
Elettaria cardamomum
Ayurveda's fragrant opener of prana and agni. Lifts kapha from the chest and sweetens digestion.
Triphala (three fruits)
Emblica + Terminalia chebula + T. bellirica
The rasayana of the colon and the eyes. Three fruits, three doshas. A formula, not a single plant — listed here because it is how Ayurveda actually practices.
Amalaki
Phyllanthus emblica
The sour rasayana that cools pitta without collapsing agni. A food of vitamin-C folklore and a classical eye-hair-digestive tonic.
Shatavari
Asparagus racemosus
The cooling, moistening rasayana of female reproductive terrain and dry vata-pitta. Not a hormone drug.
Poria
Wolfiporia extensa
The fungus that drains damp without wrecking the spleen, and quietly calms a worried shen.
Chrysanthemum
Chrysanthemum morifolium
The summer tea of wind-heat in the head and redness in the eyes. Cool, floral, and a liver-yang settler of hot afternoons.
Baikal skullcap
Scutellaria baicalensis
A cold, bitter clearer of damp-heat in the classics. Not the same as American skullcap (S. lateriflora), a nervine.
American skullcap
Scutellaria lateriflora
A true nervine of North America. Twin to lemon balm for a twitching, exhausted nervous system. Not huang qin.
Marshmallow
Althaea officinalis
The demulcent. Cold-water mucilage for dry, scraped mucosa of gut, bladder, and throat.
Aloe inner gel (not latex)
Aloe vera
Inner gel is cooling, moistening pitta food-medicine. The yellow latex (aloin) is a harsh stimulant laxative and is not kitchen herbalism.
St. John's wort
Hypericum perforatum
A solar nervine of wound and mood in European tradition — and the textbook herb-drug interaction plant. If you take any prescription, this is a pharmacist conversation, not a mood experiment.
Comfrey (external)
Symphytum officinale
A lesson in the safety layer. Once a tea of poor Europe; pyrrolizidine alkaloids can injure the liver. Modern vitalist practice: unbroken skin, short external use, never internal.
Kava
Piper methysticum
A Pacific ceremonial anxiolytic. Modern extracts have a liver-injury story that traditional water preparations of noble cultivars do not fully share — still not a casual import powder.
Ephedra (Ma huang)
Ephedra sinica
A classical exterior-releasing herb that became a dangerous weight-loss stimulant in the West. Weal lists it so the safety layer has a face: this is not a kitchen plant.
Aconite
Aconitum spp.
The most important 'do not' in East Asian herbalism. Processed fu zi is a specialist drug. Unprocessed aconite can kill. Weal will never suggest it.
Tea plant
Camellia sinensis
Bitter, astringent, slightly cooling. A damp-heat and mind herb that becomes a vata-pitta problem after 2pm.
Rose
Rosa damascena / R. rugosa
Unani and Persian medicine's cooler of the heart. TCM mei gui hua moves liver qi without peppermint's venting.
Rehmannia
Rehmannia glutinosa
Raw (sheng) clears heat and cools blood; prepared (shu) nourishes yin and jing. Heavy, cloying — the spleen must agree.
Cordyceps
Cordyceps militaris / Ophiocordyceps sinensis (wild, conservation-sensitive)
A kidney-lung tonic of high plateaus. Prefer cultivated C. militaris; wild O. sinensis is a conservation and counterfeit problem.
Andrographis
Andrographis paniculata
Relentless bitter. Ayurveda's kalmegh and TCM chuan xin lian both clear intense heat-toxin. Short courses, not a lifestyle tea.
Neem
Azadirachta indica
The bitter of skin and kapha-pitta blood. Seed oil and internal bark are not the same as a few leaves in a wash.
Bupleurum (in formulas)
Bupleurum chinense
The pivot herb of Shao-yang and of liver qi. Famous in Xiao Yao San and many Kampo sho. Not a solo tea — and high-dose / long-term has a rare liver-injury story, especially with processed formulas used carelessly.
Walnut
Juglans regia
A food that TCM uses to warm the kidney and moisten the intestine. The concordance prefers food when food will do.

It does not diagnose, treat, or replace a licensed clinician. Never stop a prescribed medicine because a plant has a story.
