Direct answer: Basil (罗勒, luólè) is sweet basil, Ocimum basilicum, an aromatic herb of the mint family (Lamiaceae). A familiar culinary herb worldwide, it carries the older Chinese name 兰香 (lánxiāng, “orchid fragrance”), which the Bencao Gangmu records as a taboo-name substitution. This classical naming is its genuine connection to the Chinese aromatic record.
Key facts
| Chinese | 罗勒 (luólè); classical 兰香 (lánxiāng) |
| Botanical source | Ocimum basilicum (family Lamiaceae) — the aerial herb |
| What it is | A leafy aromatic herb, not a wood or resin |
| Aroma | Sweet, green, spicy, slightly anise/clove |
| Traditional role | Culinary herb; 兰香 in the classical aromatic record |
Aroma profile
Direct answer: Basil is sweet and green, with a spicy, faintly anise-and-clove lift that varies by cultivar — some sweet and soft, others peppery or licorice-leaning. It is a fresh, food-adjacent note, less minty than mint and less camphoraceous than perilla; in aromatics it reads as a bright green sweetness that lifts and rounds rather than leads.
Basil is sweet and green, with a spicy, faintly anise-and-clove lift that varies by cultivar — some sweet and soft, others peppery or licorice-leaning. It is a fresh, food-adjacent note, less minty than mint and less camphoraceous than perilla. In incense and herbal aromatics it reads as a bright green sweetness that lifts and rounds a blend rather than leading it, a kitchen-garden note rather than a temple note. The cultivar variation is itself a sourcing point: “basil” is not one scent but a family of green-sweet chemotypes, and the specific cultivar (linalool-rich sweet basil versus methyl-chavicol-rich types) shifts the character.
Botanical identity
Direct answer: Basil is Ocimum basilicum, a tender annual of the mint family (Lamiaceae), native to tropical and subtropical Asia and cultivated worldwide in many culinary varieties. Its essential oil is dominated by linalool, with methyl chavicol (estragole) or eugenol in some chemotypes — the chemistry behind its sweet-green, spicy scent.
Ocimum basilicum is a tender annual herb of the mint family, native to tropical and subtropical Asia (with origins often placed in India) and cultivated worldwide in many culinary varieties. The part used is the leafy aerial herb, which carries the essential oils — dominated by linalool, with methyl chavicol (estragole) or eugenol in some chemotypes — that give sweet basil its characteristic sweet-green, spicy scent. Flora of China records the species. See Ocimum basilicum in Flora of China and Ocimum basilicum on GBIF.
The chemistry point is worth holding: the linalool-dominated sweet basil is the “classic” scent, while the estragole- and eugenol-rich chemotypes read more anise- or clove-like. This is why one basil can smell soft and sweet and another peppery — a cultivar/chemotype distinction, not a species difference.
Chinese name and terminology
Direct answer: 罗勒’s classical name is 兰香 (“orchid fragrance”), which the Bencao Gangmu records as a taboo-avoidance renaming — northerners, avoiding the taboo personal name of the Later Zhao ruler Shi Le, called 罗勒 as 兰香. The name is a renaming of the herb, not evidence that basil is an orchid or a classical incense material.
罗勒’s classical name is 兰香 — “orchid fragrance.” The Bencao Gangmu (本草纲目), in its vegetable section (菜之一), records under 罗勒 the alternative names 兰香 and 香菜, and explains the origin:
“禹锡曰：北人避石勒讳，呼罗勒为兰香。” — northerners, avoiding the taboo name of the Later Zhao ruler Shi Le, called 罗勒 as 兰香.
Li Shizhen adds, citing the Ye zhong ji (鄴中記), that Shi Hu (石虎), Shi Le’s successor, tabooed the character 勒 and “改罗勒为香菜” (changed 罗勒 to 香菜). The point for this encyclopedia is precise: 罗勒 and 兰香 are the same herb, and its “orchid fragrance” name is a taboo-avoidance renaming, not evidence that basil is a true orchid or a classical incense material. It is a culinary and garden herb whose aromatic name sits at the edge of the classical record.
The 兰香 (lan xiang) naming (read this)
Direct answer: 兰香 (“orchid fragrance”) is not a different plant but a renamed 罗勒. The Bencao Gangmu records that northerners avoided the taboo name of Shi Le by calling 罗勒 as 兰香, and Shi Hu later changed it to 香菜 — so 兰香 and 罗勒 are the same herb, and the “orchid” name is a philological accident, not a botanical or fragrance claim.
The naming story is the entry’s central, genuine classical fact:
- 罗勒 (luólè) — sweet basil, Ocimum basilicum. The base name. This entry.
- 兰香 (lánxiāng) — “orchid fragrance,” a taboo-avoidance renaming of the same herb, recorded in the Bencao Gangmu (菜之一).
- 香菜 (xiāngcài) — a further renaming by Shi Hu, also recorded.
The sequence — 罗勒 → 兰香 → 香菜 — is a documented philological chain, and its lesson is that names migrate for reasons unrelated to botany or fragrance. A reader or researcher encountering “兰香” in an older source should read it as basil (罗勒), not as a true orchid. This is a disambiguation point, not a claim that basil is an incense material.
Where does basil come from?
Direct answer: Basil originates in tropical and subtropical Asia — with origins often placed in India — and is now cultivated worldwide as a tender annual herb. It is a garden and culinary crop, not a wild-harvested aromatic.
Ocimum basilicum originates in tropical and subtropical Asia, with India often cited as its center of origin, and is now grown worldwide in countless culinary and aromatic varieties. It is fundamentally a garden herb — a tender annual grown in cultivation, not a wild-harvested botanical. This cultivated status shapes everything about it: it is a fresh, seasonal herb, used for its leafy aerial part, and its global ubiquity makes it a familiar, low-cost culinary material rather than a rare aromatic.
Why is it used in aromatics?
Direct answer: Basil is used in aromatics as a fresh, green, sweet-spicy supporting note — a kitchen-garden freshness that lifts and rounds a blend. It is not a classical burned incense material in the 香乘 tradition; its aromatic use is culinary-adjacent, and its classical claim to fame is the 兰香 naming, not a burning role.
Basil’s aromatic role is modest and food-adjacent. Its sweet-green, spicy character works as a bright green supporting note in herbal aromatics — lifting and rounding rather than leading. But it is not a classical burned incense material in the 香乘 (Xiang Cheng) tradition; its documented classical standing is culinary, and its genuine connection to the Chinese aromatic record is the 兰香 naming. The distinction to hold: basil is a garden aromatic, not a temple incense material, and its value in a blend is freshness, not depth. See how incense is made for the materials that do carry the burning canon.
How is it processed?
Direct answer: Basil is processed by harvesting the leafy aerial herb, used fresh or dried. Drying concentrates the sweet-green oils but softens the fresh character; the fresh herb is the standard culinary form, while the dried form is the rare aromatic-blending form.
The processing is simple: the aerial herb is cut and used fresh or dried. The fresh herb is the standard culinary form, carrying the full, bright, sweet-green character; drying concentrates the oils but softens the fresh, green top. For aromatic use, the dried herb (or its essential oil) is the more likely form, but basil is not a classical dried-incense ingredient — its drying is a culinary preservation step more than an incense-processing step.
What determines quality?
Direct answer: Basil quality turns on freshness (for the fresh herb) and the retention of the sweet-green, spicy aroma (for the dried herb). Cultivar/chemotype matters — the linalool-rich sweet basil differs from the anise- or clove-leaning chemotypes — so the specific variety is part of the spec.
The quality points are:
- Freshness — the fresh herb should smell bright, sweet, and green; a faded or dull scent signals age.
- Cultivar/chemotype — sweet (linalool) basil differs from the anise- or clove-leaning chemotypes; specify which character is wanted.
- Cleanliness and dryness — for the dried form, free of debris and properly dried.
These are freshness and variety checks, consistent with a culinary garden herb. The cultivar distinction is the key distinguishing nuance — “basil” is a family of green-sweet chemotypes, not one scent.
Common forms
Direct answer: Basil is used fresh (the culinary standard), dried (for aromatic blending and storage), and as an essential oil. The fresh herb carries the fullest green character; the dried herb and oil are the forms that enter aromatics.
| Form | Typical use |
|---|---|
| Fresh leaves | Culinary standard |
| Dried herb | Storage; herbal aromatic blending |
| Essential oil | Aromatics, perfumery |
The forms are states of the same leafy herb. The essential oil is the most concentrated aromatic form, but basil’s classical Chinese standing is culinary, not as a burned incense material.
In Chinese tradition
- Culinary herb: 罗勒/兰香 is a cooking herb, used fresh for its sweet-green, spicy aroma.
- 兰香 naming: the Bencao Gangmu (本草纲目) records that the herb was renamed 兰香 to avoid the taboo name of Shi Le — a genuine classical naming record.
- Garden aromatic, not temple incense: basil’s documented role is as a culinary and garden herb; it is not a burned incense material in the 香乘 tradition.
Traditional use vs modern evidence
Direct answer: The culinary use and the 兰香 naming are documented. No medical claims are made. The documented, non-medical facts are botanical identity, the Lamiaceae placement, and the classical 兰香 naming record.
- Traditional Use — 罗勒/兰香 as a culinary and garden herb in the Chinese record. Traditional usage; no medical claims.
- Historical Record — the Bencao Gangmu (菜之一) records the 罗勒 → 兰香 (→ 香菜) taboo-avoidance renaming, quoting “北人避石勒讳，呼罗勒为兰香” and citing the Ye zhong ji for Shi Hu’s change to 香菜.
- Scientific Evidence — botanical identity is established (Ocimum basilicum, Lamiaceae); its essential-oil chemistry (linalool, with estragole/eugenol in some chemotypes) is characterized. No clinical or medical efficacy claims are presented.
The documented, non-medical facts are botanical identity, the Lamiaceae placement, and the classical 兰香 naming record.

Summary
Basil (罗勒) is sweet basil, Ocimum basilicum (Lamiaceae), a culinary garden herb whose genuine connection to the Chinese aromatic record is the taboo-avoidance renaming 罗勒 → 兰香 (“orchid fragrance”) recorded in the Bencao Gangmu (菜之一). It is a fresh, green, sweet-spicy supporting note — not a classical burned incense material — and its key points are the name disambiguation (罗勒 = 兰香) and the cultivar/chemotype distinction.
FAQ
What is basil (罗勒)? Sweet basil, Ocimum basilicum, an aromatic herb of the mint family (Lamiaceae), native to tropical and subtropical Asia and cultivated worldwide in many culinary varieties. It carries the older Chinese name 兰香 (lánxiāng, “orchid fragrance”), recorded in the Bencao Gangmu (本草纲目).
Why is basil called orchid fragrance (兰香)? Because of a taboo-avoidance renaming. The Bencao Gangmu (本草纲目) records that northerners, avoiding the taboo personal name of the Later Zhao ruler Shi Le, “called 罗勒 as 兰香” (呼羅勒為蘭香), and that Shi Hu later changed it to 香菜. So 兰香 is a renaming of 罗勒, not a claim that basil is an orchid.
Is basil (罗勒) the same as 兰香? Yes. They are the same herb, Ocimum basilicum. 罗勒 is the base name and 兰香 is a taboo-avoidance alternative recorded in the classical Bencao Gangmu. The two should not be treated as different plants.
What does basil smell like? Sweet and green, with a spicy, faintly anise-and-clove lift that varies by cultivar. It is a fresh, food-adjacent note, less minty than mint and less camphoraceous than perilla, and reads in aromatics as a bright green sweetness that supports rather than leads a blend.
Is basil a classical Chinese incense material? Not in the burned-incense sense. Basil is a culinary and garden herb; its classical claim to fame is the 兰香 naming recorded in the 本草纲目, not a role in the 香乘 incense tradition. Its aromatic use is as a fresh green note, not a burned temple material.
What is the difference between basil and perilla? Both are Lamiaceae herbs, but basil (Ocimum basilicum) is sweet-green and spicy, while perilla (Perilla frutescens, 紫苏) is more minty and anise-like with a distinctive shiso character. They are different genera with different aromatic profiles, though both are leafy culinary herbs.
Why does one basil smell different from another? Because of cultivar and chemotype. The linalool-dominant “sweet” basil is soft and classic, while the methyl-chavicol (estragole) and eugenol chemotypes read more anise- or clove-like. They are all Ocimum basilicum, but the specific variety shifts the green-sweet character.
