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

food

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

food

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

caution

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

generally-safe

The household rasayana of India. Aromatic, sattvic, and a daily tea more than a heroic cure.

Brahmi

Bacopa monnieri

caution

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

caution

A cooling connective-tissue and mind herb that sits in both Ayurveda and southern Chinese folk use.

Licorice

Glycyrrhiza glabra / G. uralensis

caution

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

food

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

generally-safe

The great surface-qi tonic. Builds wei qi over weeks. Not for a fever you already have.

Schisandra

Schisandra chinensis

caution

Five flavors in one berry: astringe jing, calm shen, moisten lung, and remember that sour holds what is leaking.

Goji

Lycium barbarum

food

A food-tonic for liver blood and kidney yin. Eyes and nights. Sweet, not a superfood stunt.

Reishi

Ganoderma lucidum / G. sichuanense

generally-safe

The spirit mushroom of the classics: calm shen, nourish heart qi. Bitter, slow, and not a latte flavoring.

Asian ginseng

Panax ginseng

caution

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

practitioner-only

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

food

Bo he vents wind-heat and soothes liver qi; peppermint is the Western carminative of stuck guts and tense brows.

Chamomile

Matricaria chamomilla

generally-safe

The gentle bitter of European and Unani pharmacies. Children, guts, and tempers. A tissue-state herb of irritation with tension.

Lemon balm

Melissa officinalis

generally-safe

Avicenna's heart herb. Lifts the spirits without caffeine and cools a fluttery chest.

Passionflower

Passiflora incarnata

caution

A circular-thought nervine of the Americas. For the mind that will not stop arranging the furniture.

Milky oats / oatstraw

Avena sativa

food

The trophorestorative of a frayed nervous system. Food-like, slow, and almost never the wrong first move.

Nettle

Urtica dioica

food

Mineral green. Leaf as nutritive and mild alterative; root is a different prostate-adjacent medicine.

Dandelion

Taraxacum officinale

food

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

generally-safe

Mediterranean hepatic seed. Silymarin extracts are a modern concentrated form — still not a license to drink harder.

Hawthorn

Crataegus monogyna / C. laevigata

caution

Europe's heart trophorestorative; Chinese shan zha is more a greasy-food digestive that also moves blood. Related, not identical.

Elder

Sambucus nigra

caution

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

caution

A specific of the Eclectics for septic, dull, and decaying tissue states — not a daily 'immune boost' candy.

Valerian

Valeriana officinalis

caution

A heavy hypnotic that helps some and agitates others. If it makes you angry, you are in the other group.

Lavender

Lavandula angustifolia

generally-safe

Cooling aromatic of the nervous system. Tea and scent first; essential oil internally is not folk tea.

Rosemary

Salvia rosmarinus

food

A circulatory aromatic of memory and cold stagnation. Culinary first.

Thyme

Thymus vulgaris

food

A pungent antimicrobial aromatic of the respiratory mucosa. Kitchen steam is still medicine.

Fennel

Foeniculum vulgare

food

The after-meal seed of India and the Greco-Arabic world. Warms and moves a cramped gut without ginger's fire.

Cardamom

Elettaria cardamomum

food

Ayurveda's fragrant opener of prana and agni. Lifts kapha from the chest and sweetens digestion.

Triphala (three fruits)

Emblica + Terminalia chebula + T. bellirica

caution

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

food

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

caution

The cooling, moistening rasayana of female reproductive terrain and dry vata-pitta. Not a hormone drug.

Poria

Wolfiporia extensa

generally-safe

The fungus that drains damp without wrecking the spleen, and quietly calms a worried shen.

Chrysanthemum

Chrysanthemum morifolium

generally-safe

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

practitioner-only

A cold, bitter clearer of damp-heat in the classics. Not the same as American skullcap (S. lateriflora), a nervine.

American skullcap

Scutellaria lateriflora

caution

A true nervine of North America. Twin to lemon balm for a twitching, exhausted nervous system. Not huang qin.

Marshmallow

Althaea officinalis

generally-safe

The demulcent. Cold-water mucilage for dry, scraped mucosa of gut, bladder, and throat.

Aloe inner gel (not latex)

Aloe vera

caution

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

practitioner-only

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

avoid

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

practitioner-only

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

avoid

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.

avoid

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

food

Bitter, astringent, slightly cooling. A damp-heat and mind herb that becomes a vata-pitta problem after 2pm.

Rose

Rosa damascena / R. rugosa

food

Unani and Persian medicine's cooler of the heart. TCM mei gui hua moves liver qi without peppermint's venting.

Rehmannia

Rehmannia glutinosa

practitioner-only

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)

caution

A kidney-lung tonic of high plateaus. Prefer cultivated C. militaris; wild O. sinensis is a conservation and counterfeit problem.

Andrographis

Andrographis paniculata

practitioner-only

Relentless bitter. Ayurveda's kalmegh and TCM chuan xin lian both clear intense heat-toxin. Short courses, not a lifestyle tea.

Neem

Azadirachta indica

practitioner-only

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

practitioner-only

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

food

A food that TCM uses to warm the kidney and moisten the intestine. The concordance prefers food when food will do.
