Direct answer: Grapefruit (葡萄柚, pútáoyòu) is the fruit and rind of Citrus × paradisi, a modern cultivated citrus hybrid in the rue family (Rutaceae). Its peel carries a fresh, bittersweet, green-slightly-woody citrus scent from its essential oil, and it is a modern essential-oil fragrance material, not a classical Chinese incense ingredient. It is distinct from the pomelo (柚), its larger ancestral parent.
Key facts

| Botanical source | Citrus × paradisi (family Rutaceae) — the fruit rind and essential oil |
| What it is | A modern cultivated hybrid citrus, not a classical Chinese fragrance fruit |
| Aroma | Citrus, fresh, bittersweet, green, slightly woody |

Aroma profile
葡萄柚 (grapefruit) is fresh, bright, and bittersweet, with a green, slightly woody edge that distinguishes it from the cleaner sweetness of lemon or orange. It is a top note with more body than lemon — the bittersweet, slightly sulfurous green character comes from the compound nootkatone and the mercaptan compounds in the rind oil.
A provenance note (read this)
葡萄柚 (grapefruit) is a modern essential-oil material, not a classical Chinese 香材:
- Citrus × paradisi is a recent cultivated hybrid — botanically a pomelo (柚, Citrus maxima) crossed with the sweet orange (Citrus sinensis) — first described from the Caribbean in the 18th century. Flora of China does not record it as a native species.
- The Chinese name 葡萄柚 is modern, a literal rendering of “grapefruit”; the grapefruit as a fragrance note is a modern essential-oil and Western-perfumery tradition, absent from the classical 香材 canon.
- It is not the same as 柚皮 (pomelo peel, Citrus maxima) — its larger, older ancestor, which has its own entry.
This page records it honestly as a modern citrus essential oil — no classical Chinese origin is claimed, and none is fabricated.
The grapefruit / pomelo distinction (read this)
葡萄柚 and 柚 are closely related but distinct:
- 葡萄柚 (grapefruit) — Citrus × paradisi, a small modern hybrid (pomelo × sweet orange), used for essential oil. This entry.
- 柚 / 柚皮 (pomelo / pomelo peel) — Citrus maxima, the largest citrus, a native Southeast Asian species long grown in southern China; its peel is a traditional citrus note.
The grapefruit is a modern descendant of the pomelo, but they are different materials, different sizes, and different Chinese identities. Specify the species when sourcing.
Botanical source and origin
Citrus × paradisi is a small evergreen tree of the rue family (Rutaceae), a cultivated hybrid of the pomelo (Citrus maxima) and the sweet orange. It arose in the West Indies in the 18th century and is now grown worldwide. GBIF records the species; it is a modern crop with no native Chinese wild population. The fragrant part is the rind oil.
In modern use
- Essential oil: grapefruit oil, cold-pressed from the peel, is a fresh bittersweet top note in perfumery, home fragrance, and aromatherapy.
- Home fragrance: grapefruit scents appear widely in modern candles, diffusers, and room sprays.
- Not classical Chinese incense: grapefruit has no place in the classical 香材 canon; its use is modern essential-oil perfumery.
Traditional use vs modern evidence
There is no classical Chinese incense record for 葡萄柚 (grapefruit); its position is entirely modern. We make no medical claims. The documented facts are botanical identity, the Rutaceae placement, and its modern essential-oil role.
Quality and sourcing notes
Practical points for buyers:
- 葡萄柚 (grapefruit) here is Citrus × paradisi; expect a fresh, bittersweet, green-slightly-woody rind scent from cold-pressed peel oil.
- Distinguish it from 柚皮 (pomelo peel, Citrus maxima) — its larger, older ancestor with a traditional Chinese citrus note.
- Grapefruit is a top note; it is usually blended rather than burned alone.
Safety
Incense combustion produces smoke and particulate matter. Burn in a well-ventilated space, avoid inhaling concentrated smoke, and keep away from children and pets. Citrus oils can be skin-irritating at high concentration; use as directed. This is editorial knowledge content, not medical advice.
