4 Science-Backed Benefits of Coriander

From: Verywell Health

Coriander, a member of the carrot family, is used worldwide as both a spice and a traditional remedy. In the United States, coriander typically refers to the seeds, which are valued for their potential health benefits, while the leaves are commonly known as cilantro.

1. Antioxidant Benefits

Coriander contains several antioxidants. Antioxidants help fight free radicals, which are unstable molecules that can damage cells in the body. Antioxidants can support immune health and reduce inflammation, while also exhibiting neuroprotective effects.

However, much of this research has been performed in test tubes and animal studies, and human data are lacking.

2. May Support Heart Health

Coriander leaves have been found to contain flavonoids, essential phytochemicals that act as antioxidants. According to one review, the flavonoids in coriander inhibit the angiotensin-converting enzyme (ACE), leading to more relaxed arteries and, as a result, lowered blood pressure.

As promising as these results are, human research on coriander for high blood pressure (hypertension) is severely lacking. More research is needed in this area.

3. May Reduce Anxiety

Coriander is widely used in traditional medicine for anxiety. Preliminary research has shown coriander to have antianxiety effects. It may work by modulating negative emotions that arise in the brain.

Yet, human trials need to be conducted to confirm coriander's role in treating anxiety before it can be recommended.

4. May Offer Skin Protection

Lab research has revealed that coriander increases the production of procollagen type 1, a precursor to collagen, which is the most abundant protein in human skin.

In the study, coriander was also shown to thicken the dermal layer of the skin and prevent the formation of free radicals, which are often present in sun-damaged skin.

In another study, coriander essential oil showed the most potential for treating sun damage compared to other essential oils. Researchers found that coriander inhibited various enzymes that may lead to photoaging (cumulative sun damage that prematurely ages the skin).

Linalool, the primary bioactive ingredient in coriander, was believed to be the primary component responsible for these effects.

Once again, however, additional studies should be conducted before coriander can be recommended for treating sun-damaged skin.

4 Science-Backed Benefits of Coriander

From: Verywell Health

Coriander, a member of the carrot family, is used worldwide as both a spice and a traditional remedy. In the United States, coriander typically refers to the seeds, which are valued for their potential health benefits, while the leaves are commonly known as cilantro.

香菜为伞形科（胡萝卜科）植物，在世界各地既作调味香料，也见于传统草本应用。在美国，人们通常用coriander指代散发独特健康价值的香菜籽，而cilantro则特指其叶片。

spice /spaɪs/ 作动词，表示“在…中加香料”，英文解释为“to use spice to add flavour to food or drink”如：coffee spiced with cinnamon 加了桂皮调味的咖啡。

作名词，1）表示“（调味）香料”，英文解释为“a substance made from a plant, used to give a special flavour to food”举个🌰：Cinnamon, ginger, and cloves are all spices. 肉桂、姜和丁香都属于香料。

2）表示“调剂品；额外的刺激（或趣味）”，英文解释为“something that makes something else more exciting and interesting”举个🌰：A scandal or two adds a little spice to office life. 一两条丑闻为办公室生活平添了一点乐趣。

1. Antioxidant Benefits 抗氧化作用

Coriander contains several antioxidants. Antioxidants help fight free radicals, which are unstable molecules that can damage cells in the body. Antioxidants can support immune health and reduce inflammation, while also exhibiting neuroprotective effects.

香菜含有多种抗氧化成分。抗氧化物可对抗自由基——这类不稳定分子可能对机体细胞造成损伤。相关成分通常与支持免疫功能、减轻炎症反应及一定的神经保护效应相关。

antioxidant /ˌæn.tiˈɒk.sɪ.dənt/ 表示“抗氧化剂，阻氧化剂，防老（化）剂”，英文解释为“a substance that slows down the rate at which something decays because of oxidization”

free radical /ˌfriː ˈræd.ɪ.kəl/ 表示“自由基，游离基”，英文解释为“a molecule that has an extra electron and therefore reacts very easily with other molecules”举个🌰：Free radicals have been implicated in cancer and many other serious diseases. 游离基是罹患癌症和许多其他严重疾病的潜在原因之一。

molecule /ˈmɒl.ɪ.kjuːl/ 表示“分子”，英文解释为“the smallest unit, consisting of a group of atoms, into which a substance can be divided without a change in its chemical nature”举个🌰：A molecule of water consists of two atoms of hydrogen and one atom of oxygen. 水分子由两个氢原子和一个氧原子构成。

However, much of this research has been performed in test tubes and animal studies, and human data are lacking.

不过，现有证据多来自试管实验及动物研究，人体层面的数据仍然不足。

test tube /ˈtest ˌtjuːb/ 表示“试管”，英文解释为“a small glass tube with one closed and rounded end, used in scientific experiments”

2. May Support Heart Health 或有助于心血管健康

Coriander leaves have been found to contain flavonoids, essential phytochemicals that act as antioxidants. According to one review, the flavonoids in coriander inhibit the angiotensin-converting enzyme (ACE), leading to more relaxed arteries and, as a result, lowered blood pressure.

研究发现，香菜叶富含黄酮类化合物，这是一类具有抗氧化活性的关键植物化学物。有综述指出，其中部分黄酮可能抑制血管紧张素转化酶（ACE），从而促进血管舒张，降低血压。

As promising as these results are, human research on coriander for high blood pressure (hypertension) is severely lacking. More research is needed in this area.

尽管上述结果具有一定前景，但针对香菜干预高血压的人体研究仍十分有限，该领域尚需更多临床证据加以验证。

3. May Reduce Anxiety 可能有助于缓解焦虑

Coriander is widely used in traditional medicine for anxiety. Preliminary research has shown coriander to have antianxiety effects. It may work by modulating negative emotions that arise in the brain.

传统医学中，香菜常用于焦虑的调理。初步研究证实其具有抗焦虑效果，机制可能与其调节脑内负面情绪有关。

preliminary表示“预备性的；初步的；开始的”，英文解释为“happening before a more important action or event”如：preliminary results / findings / enquiries 初步结果 / 发现 / 调查，举个🌰：After a few preliminary remarks he announced the winners. 说了几句开场白之后，他即宣布优胜者名单。

modulate /ˈmɒdʒ.ə.leɪt/ 1）表示“改变（嗓音）的音量（或音质等），调节（声音）”，英文解释为“to change the style, loudness, etc. of something such as your voice in order to achieve an effect or express an emotion”举个🌰：His gentle introductory tone modulates into a coach's pre-game pep talk. 他语气温和的开场白变成了足球教练赛前鼓舞士气的慷慨陈词。

2）表示“（音乐）变调”，英文解释为“to change from one musical key to another”举个🌰：Here we modulate from G major to A minor. 这儿我们从G大调变成A小调。

Yet, human trials need to be conducted to confirm coriander's role in treating anxiety before it can be recommended.

然而，在提出明确应用建议之前，仍需严谨的人体试验以确认其在焦虑干预中的实际作用。

4. May Offer Skin Protection 可能具有皮肤保护作用

Lab research has revealed that coriander increases the production of procollagen type 1, a precursor to collagen, which is the most abundant protein in human skin.

实验室研究发现，香菜能够促进Ⅰ型前胶原蛋白的生成。作为胶原蛋白的前体，Ⅰ型前胶原蛋白与胶原蛋白的关系密切，而后者正是人体皮肤中含量最丰富的蛋白质。

表示“先驱，先锋；先兆，前兆”，英文解释为“something that happened or existed before another thing, especially if it either developed into it or had an influence on it”举个🌰： Biological research has often been a precursor to medical breakthroughs. 生物学研究往往是医学突破的先驱。

collagen /ˈkɒl.ə.dʒən/ 表示“胶原蛋白”，英文解释为“a protein found especially in the joints (= places where two bones are connected) of humans and animals”

📍collagen implant/injection 表示“（作为整形美容手术的）胶原蛋白植入（或注射）”，英文解释为“an injection of collagen into the lips or skin to make the lips appear larger or the skin appear younger and smoother”

In the study, coriander was also shown to thicken the dermal layer of the skin and prevent the formation of free radicals, which are often present in sun-damaged skin.

研究同时发现，相关成分或有助于增强真皮层结构，并抑制与日晒损伤相关的自由基反应。

thicken /ˈθɪk.ən/ 表示“（使）变厚（或浓、粗、密等）”，英文解释为“to (cause to) become thicker”举个🌰：Thicken the sauce with a little flour. 加少许面粉把酱汁调稠。

In another study, coriander essential oil showed the most potential for treating sun damage compared to other essential oils. Researchers found that coriander inhibited various enzymes that may lead to photoaging (cumulative sun damage that prematurely ages the skin).

另有研究显示，在多种精油中，香菜精油在应对光损伤方面展现出较高潜力。研究人员观察到，其成分可能抑制多种与光老化（由累积日晒引发的皮肤过早老化）相关的酶活性。

essential oil /ɪˌsen.ʃəl ˈɔɪl/ 表示“（香）精油”，英文解释为“an oil, usually with a strong smell, that is taken from a plant and is used to make perfume, or for rubbing into a person's body during massage”举个🌰：Lavender, peppermint, and jasmine are essential oils that are widely available. 熏衣草油、薄荷油和茉莉香精是很多地方都可以买到的精油。

Linalool, the primary bioactive ingredient in coriander, was believed to be the primary component responsible for these effects.

这些功效主要源于香菜中的核心生物活性成分——芳樟醇。

ingredient /ɪnˈɡriː.di.ənt/ 1）表示“（成功的）要素，因素”，英文解释为“one of the parts of something successful”举个🌰：Trust is a vital ingredient in a successful marriage. 信任是婚姻幸福的重要因素。

Once again, however, additional studies should be conducted before coriander can be recommended for treating sun-damaged skin.

然而，在将香菜正式用于治疗光损伤皮肤之前，仍需开展进一步的研究加以验证。
