What is the geographical distribution of this plant?

This plant is native to the subtropical and temperate forests of southern Japan, Taiwan, and parts of southeast China. It typically grows in the understory of moist, shaded woodlands where the climate remains relatively mild. Within its natural range, the species can be found spanning from sea level up to moderate elevations in mountainous regions. Due to its fragrant flowers and attractive foliage, it has been widely introduced to various temperate gardens across Europe and North America. These cultivated populations often thrive in similar humid, sheltered environments to their original habitats.

Evidence Level: ★☆☆☆☆

How is this plant cultivated?

This plant requires well-drained, slightly acidic soil and a location that provides partial shade with protection from harsh, drying winds.

It thrives best in USDA hardiness zones 7 through 9 where temperatures remain relatively moderate. Regular watering is essential to keep the soil consistently moist, though you must avoid allowing the roots to sit in standing water. Mulching around the base helps maintain moisture levels and stabilizes soil temperature during seasonal shifts.

Once established, the shrub is relatively low-maintenance but should be fertilized lightly in early spring to support its fragrant blooms.

What parts of this plant are used medicinally?

This plant is used medicinally through its whole plants, including the roots, stems, leaves, and flowers. The fragrant flowers are often utilized in aromatherapy or infusions to calm the nervous system. Extracts from the stems and bark contain compounds that can stimulate circulation when applied topically. However, extreme caution must be taken because many parts of the plant are highly toxic if ingested in large amounts. Traditional applications focus on diluted preparations to avoid the dangerous effects of its potent chemical constituents.

According to a study published by "Bioorganic chemistry", 26 structurally diverse daphnane diterpenoids (1-26), including 6 undescribed ones (1-6), were isolated from the whole plants of Daphne odora. Among these, 7 daphnane diterpenoids showed significant inhibitory effect on the NSCLC cell line HCC827. Compounds 1 and 2 were the most active, with IC50 values of 3.57 ± 0.32 and 4.35 ± 0.14 μM, respectively. These 2 compounds could significantly induce cell cycle arrest at the G2/M phase and cause cell apoptosis. Furthermore, transcriptome sequencing analysis revealed that 1 and 2 significantly suppressed ATR-mediated DNA damage response and cell cycle checkpoint.

What traditional systems uses this plant?

This plant, known as Daphne odorata, has been utilized in Traditional Chinese Medicine to treat various ailments such as skin conditions and gastrointestinal issues. Historically, its fragrant flowers were highly valued in various cultures for making perfumes and aromatic oils. Some ancient herbalists used processed parts of the plant to address inflammatory conditions or to act as a topical remedy. Because certain parts of the shrub contain toxic compounds, traditional practitioners applied precise preparation methods to mitigate risks. These historical applications demonstrate the plant's long-standing significance in both medicinal and sensory practices.

According to a study published by "Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica", there is no obvious change between the present distribution ranges of the wild Daphnes Cortex and its historical records. The current total reserve of the wild Daphnes Cortex in the 4 provinces surveyed is no more than 600 tons. Researchers conducted a resources survey in 23 counties across Shanxi, Gansu, Sichuan and Qinghai provinces. Only one cultivated resource was found in a mountain at an altitude of about 2 800 m in Kang county of Gansu province. This specific cultivated area had a cropping scope of about 33 000 m².
