Occasional worry, nervous tension, and restlessness are part of everyday life — but when they persist they can be exhausting. Traditional Chinese Medicine (TCM) has addressed what we now call anxiety for centuries, under names like constraint syndrome (yu zheng) and visceral agitation (zang zao). On this page we walk through what modern research says about diet and mood, the safety points to keep in mind, and the classical TCM patterns and food-therapy recipes traditionally used to support calm and balance.
Research into the connection between diet and mood has grown rapidly, and the overall picture is that the two are closely linked — though most findings are associations rather than proof of cause and effect.
A 2019 meta-analysis of randomized controlled trials published in Psychosomatic Medicine found that dietary improvement was associated with reductions in symptoms of depression and anxiety (PMID: 30720698). The authors pooled controlled trials of dietary interventions and reported that improving overall diet quality was linked to better mood outcomes.
At the single-ingredient level, a 2025 meta-analysis published in Nutrition Reviews compared saffron with selective serotonin reuptake inhibitors (SSRIs) across randomized controlled trials and reported that saffron was associated with improvements in symptoms of depression and anxiety comparable to SSRIs (PMID: 38913392). Saffron has a long history of use in traditional medicine, which makes this an area of active interest.
Taken together, this literature suggests diet may be one modifiable factor in supporting emotional balance — but it is not a substitute for medical evaluation or treatment when anxiety is persistent or severe.
The ingredients mentioned on this page — including licorice root (Gan Cao), jujube (Chinese dates), sour jujube seed (Suan Zao Ren), longan, lily bulb, lotus seed, Chinese yam, and goji berry — are used in traditional recipes and are generally considered safe in culinary amounts. However, some deserve caution: licorice root may raise blood pressure and interact with blood-pressure and potassium-depleting medications; sour jujube seed may enhance the effect of sedatives and should not be combined with sleep medication or alcohol; longan and jujube are naturally high in sugar, which matters for people managing blood sugar; and goji berry may interact with blood-thinning medications such as warfarin. Wheat-based recipes contain gluten and are not suitable for people with celiac disease. If you are pregnant, nursing, taking prescription medication, or have a chronic health concern, speak with a qualified healthcare provider before making significant dietary changes.

In Traditional Chinese Medicine, anxiety falls within the categories of constraint syndrome (yu zheng), visceral agitation (zang zao), palpitations, and insomnia. It is understood as arising from emotional strain and excessive worry that may cause liver qi constraint; the constrained qi may transform into fire or overact on the spleen, and over time this may lead to heart-spleen deficiency with the mind losing nourishment, or constrained fire injuring yin with phlegm-heat disturbing the mind. The condition involves the heart, liver, and spleen — and the approach is tailored to which pattern is present.
In TCM, this concern is differentiated into several patterns, each with a treatment principle and a classical herbal formula:
Treatment principle: Soothe the Liver and Regulate Qi, Relieve Constraint
Formula: Chaihu Shugan San (Bupleurum Liver-Coursing Powder) — from Jingyue's Complete Works
Treatment principle: Soothe the Liver and Clear Heat, Relieve Constraint
Formula: Dan Zhi Xiao Yao San (Moutan and Gardenia Free and Easy Wanderer Powder) — from Summary of Internal Medicine
Treatment principle: Regulate Qi and Activate Blood, Resolve Stasis
Formula: Xuefu Zhuyu Tang (Blood Mansion Stasis-Expelling Decoction) — from Corrections of Errors in Medical Classics
Treatment principle: Supplement the Heart and Spleen, Nourish Blood and Quiet the Spirit
Formula: Guipi Tang (Restore the Spleen Decoction) — from Formulas to Aid the Living
Treatment principle: Nourish the Heart and Calm the Spirit
Formula: Ganmai Dazao Tang (Licorice, Wheat and Jujube Decoction) — from Synopsis of the Golden Chamber
Treatment principle: Enrich Yin and Subdue Fire, Nourish the Heart and Quiet the Spirit
Formula: Tianwang Buxin Dan (Celestial Emperor's Heart-Tonifying Pill) — from A Complete Book of Effective Prescriptions for Women
Treatment principle: Boost Qi and Settle Fright, Calm the Spirit
Formula: Anshen Dingzhi Wan (Calm the Spirit and Settle the Will Pill) — from Yi Xue Xin Wu
Treatment principle: Clear Heat and Resolve Phlegm, Harmonize the Stomach and Quiet the Spirit
Formula: Huanglian Wendan Tang (Coptis Gallbladder-Warming Decoction) — from Liu Yin Tiao Bian
These formulas are for reference under TCM syndrome differentiation and should only be used under the guidance of a qualified practitioner.
Food therapy is the gentler, everyday counterpart to herbal formulas. The following preparations come from classical TCM dietary literature and use food-grade ingredients traditionally associated with calming the mind. As with all traditional recipes, they are offered for reference and should be used under the guidance of a qualified practitioner.

The condition involves the heart, liver, and spleen; it tends to be excess in the early stage (qi stagnation, phlegm, fire, blood stasis) and becomes deficiency over time.
Emerging research suggests diet and mood are linked. A 2019 meta-analysis of randomized controlled trials published in Psychosomatic Medicine found that dietary improvement was associated with reductions in symptoms of depression and anxiety (PMID 30720698). These findings are suggestive rather than proof of cause and effect, and they are not a substitute for medical evaluation.

This is preliminary, suggestive evidence, not a recommendation to self-treat.
The recipes on this page use food-grade ingredients that are generally recognized as safe in culinary amounts. However, some ingredients can interact with medications — for example, licorice root may affect blood pressure, and sour jujube seed may enhance the effect of sedatives. If you take prescription medicine, are pregnant or nursing, or have a chronic health concern, speak with a qualified healthcare provider before making significant dietary changes.
In Traditional Chinese Medicine, anxiety falls within the categories of constraint syndrome (yu zheng), visceral agitation (zang zao), palpitations, and insomnia. It is understood as arising from emotional strain and worry that may cause liver qi constraint, which over time can transform into fire, deplete the heart and spleen, or generate phlegm-heat. The approach is tailored to the specific pattern present.
