Pig Heart Soup with Arborvitae Seed: TCM Remedy for Insomnia & Anxiety

Introduction to Medicinal Diet

Semen Platycladi (Platycladi Semen) and Pig Heart Soup is a classic TCM sedative medicinal food with a long history, originating from the *Shiliao Bencao* (Materia Medica for Dietotherapy) and the cumulative experience of generations of herbalists. This soup features pig heart as the main ingredient, Semen Platycladi as the sovereign herb, and is complemented by auxiliary ingredients such as red dates (Fructus Jujubae) and fresh ginger (Rhizoma Zingiberis Recens). It is slowly simmered over low heat to preserve the freshness of the ingredients while fully releasing the nourishing effects of the herbs.

Bai Zi Ren (Platycladi semen) is the seed kernel of *Platycladus orientalis* (Cupressaceae). It is neutral in nature and sweet in flavor, entering the Heart (HT), Kidney (KI), and Large Intestine (LI) meridians. Pig heart, according to the principle of “like treats like” (using organs to nourish corresponding organs), can supplement the Heart and nourish the Blood. When combined, they integrate medicinal power with dietary nourishment. The resulting soup is clear with a slight yellow tint, aromatic in fragrance, and sweet and moistening on the palate. It is an excellent remedy for nourishing the Heart in spring and regulating the Spirit throughout the four seasons.

The cultural heritage of medicinal diet (yaoshan)

In traditional Chinese dietary culture, the use of animal organs in cooking has a long history. *Bai Zi Ren* (Platycladus orientalis seed), as a key herb for calming the spirit, is listed as a top-grade substance in *Shen Nong’s Herbal Classic*, which states that it “treats palpitations, calms the five viscera, and boosts *qi*.” *Bai Zi Ren* and pig heart soup is a classic representation of the wisdom of “food and medicine sharing the same origin.” For thousands of years, it has been widely passed down among the people, especially favored by scholars and those suffering from insomnia.

Efficacy of Medicinal Diet

The primary effects of Bai Zi Ren (Platycladi Semen) and Pig Heart Soup are to nourish the heart and calm the spirit, as well as to supplement blood and moisten the intestines. Bai Zi Ren nourishes heart qi and calms the spirit, while pig heart supplements the heart and nourishes blood. Their synergistic action produces significant regulatory effects on symptoms such as insomnia with excessive dreaming, palpitations and severe palpitations, forgetfulness, and irritability, which arise from heart blood deficiency and the heart failing to be nourished.

Additionally, *Platycladi Semen* (Chinese arborvitae seed) is oily and rich in fatty oils, effectively moistening the intestines and promoting bowel movements, making it suitable for constipation due to intestinal dryness and fluid deficiency. Pig heart is rich in protein, B vitamins, iron, zinc, and other nutrients, helping to improve qi and blood deficiency, restore energy, and enhance memory. Long-term moderate consumption also provides health benefits such as boosting intellect, calming the spirit, and delaying aging.

Modern nutrition perspective

From a modern nutritional perspective, pig heart contains abundant coenzyme Q10 and taurine, which protect myocardial function; Semen Platycladi (Platycladus orientalis, Chinese arborvitae seed) is rich in unsaturated fatty acids and phospholipids, which help regulate central nervous system excitability. The combination improves sleep quality and provides high-quality nutritional supplements for the body.

Functions of Traditional Chinese Medicine

In Traditional Chinese Medicine, the Heart governs the blood and vessels and houses the spirit. If excessive worry and rumination overwork the Heart and Spleen, or if chronic illness leads to deficiency and excessive blood loss, these can result in Heart Blood Deficiency and malnourishment of the Heart spirit, manifesting symptoms such as palpitations, insomnia, and dream-disturbed sleep. Platycladus orientalis seed (Bai Zi Ren) enters the Heart Meridian (HT); its nature is neutral and its quality moistening. It nourishes the Heart and calms the spirit without causing cloying or obstructing the Stomach. Pig heart directly tonifies the qi and blood of the Heart. When used together, these two address both the root and the manifestation.

Biota seed (Semen Platycladi) also enters the Kidney meridian (KI), capable of supplementing Kidney qi. When Kidney water is sufficient, it can ascend to nourish the Heart, preventing Heart fire from becoming hyperactive, and the Heart spirit will naturally be at peace. At the same time, its moistening-dryness property can alleviate accompanying symptoms such as dry mouth and constipation caused by hyperactive Heart fire. The fresh ginger (Rhizoma Zingiberis Recens) added to the decoction warms the middle and disperses cold, harmonizes the stomach and stops vomiting; jujube (Fructus Jujubae) tonifies the middle and supplements qi, nourishes blood and calms the spirit; Poria (Poria cocos) (if selected) percolates dampness and strengthens the spleen. Together, they assist the main herb in exerting a more comprehensive regulating effect.

Channel Tropism and the Significance of Compatibility

The compositional rationale of Platycladi Semen and Pig Heart Soup embodies the TCM principle of “nourishing both the body and spirit (xíng shén gòng yǎng).” The pig heart enters the Heart Meridian (HT) and directly tonifies the heart substance as a “flesh-and-blood” substance (xuè ròu yǒu qíng zhī pǐn). Platycladi Semen (Platycladi Semen / Chinese arborvitae seed) enters the Heart (HT), Kidney (KI), and Large Intestine (LI) Meridians, comprehensively regulating the circulation of body fluids and essence-qi (jīng qì) across the Upper, Middle, and Lower San Jiao (Triple Energizers). It is particularly suitable for insomnia due to Heart-Kidney Disharmony (xīn shèn bù jiāo)—namely, Kidney Water Deficiency (shèn shuǐ bù zú) with Heart Fire Hyperactivity (xīn huǒ kàng shèng), presenting as irritability with sleeplessness (xīn fán bù mèi) and soreness and weakness of the lower back and knees (yāo xī suān ruǎn). In this context, Platycladi Semen both nourishes the Heart and benefits the Kidney, serving a pivotal bridging role.

Suitable Population

Boziren Pig Heart Soup (Platycladi Semen and Pig Heart Decoction) is especially suitable for the following groups: first, mental workers and students who suffer from chronic insomnia, frequent dreaming with easy awakening, and memory decline; second, individuals with general deficiency due to Heart Blood Deficiency presenting with palpitations, shortness of breath, sallow complexion, and dizziness/vertigo; third, menopausal women who often experience irritability, insomnia, and hot flashes, as consuming this soup can help calm the mind and settle the spirit (tranquilize the heart and quiet the mind).

Furthermore, this soup is also suitable for middle-aged and young adults with habitual constipation accompanied by palpitations and insomnia, as well as those in a sub-health state, under high mental stress, or prone to tension and anxiety, as a daily dietary supplement. For elderly individuals presenting with heart qi deficiency, frequent nocturia, and shallow, short sleep, moderate consumption may also be beneficial.

Contraindicated Populations

Although Bai Zi Ren (Platycladi Semen) and pig heart soup is mild in nature, it is not suitable for everyone. Individuals with a constitutional pattern of phlegm-dampness exuberance, characterized by a thick, greasy tongue coating, poor appetite, and abdominal distension, should avoid overconsumption. This is because Bai Zi Ren is moistening in quality and pig heart is somewhat fatty, which may aggravate dampness and impair the stomach, thereby increasing the burden on the spleen and stomach. It is also contraindicated for insomnia due to internal harassment of phlegm-heat, presenting with chest tightness, copious phlegm, a bitter taste in the mouth, and a yellow, greasy tongue coating.

Additionally, during an externally-contracted Wind-Cold or Wind-Heat Common Cold, as well as during episodes of acute diarrhea or dysentery, consumption should be temporarily ceased to avoid “locking the pathogen inside” (闭门留寇) or exacerbating the condition. Pregnant women should only consume under a physician’s guidance, as this preparation contains certain pharmacological components. It is contraindicated in those with an allergy to Pig Heart or Semen Platycladi (Platycladus orientalis seed). Patients with hypercholesterolemia should consume in small amounts, or remove the fatty portions of the Pig Heart.

Ingredient formula proportions

Standard Formula (serves 2–3 people): 1 fresh pig heart (approx. 250–300 g), 10–15 g Platycladi Semen (Bai Zi Ren, Arborvitae Seed), 6–8 Fructus Jujubae (Hong Zao, Chinese Red Date, approx. 30 g), 3 slices Zingiberis Rhizoma Recens (Sheng Jiang, Fresh Ginger, approx. 10 g), 10 g Poria (Fu Ling, optional), and salt to taste. Bai Zi Ren (Arborvitae Seed) is the sovereign (chief) herb, with its dosage strictly controlled at 10–15 g—too little weakens the therapeutic effect, while too much makes the formula overly cloying and greasy.

As for supplementary ingredients, red dates (Fructus Jujubae, Ziziphus jujuba) with large size, thick flesh, and deep red color are preferred. For ginger (Rhizoma Zingiberis Recens, Zingiber officinale), select old ginger and slice it. If adding Poria (Wolfiporia extensa, Poria cocos), it is recommended to use Yunnan Poria, cut into small pieces and simmered together with the soup. The water ratio should be 5–6 times the total weight of the ingredients, approximately 1500–1800 ml, and the soup should be reduced to 800–1000 ml. This ratio allows the full release of medicinal effects while maintaining a balanced taste, neither too strong nor too weak.

Preparation Method

Step One: Prepare the pork heart. Split the fresh pork heart open and rinse thoroughly with clean water to remove internal static blood clots and fascia. Slice it into thin pieces about 0.5 cm thick, place in a bowl, and add a small amount of cooking wine and water. Soak for 15 minutes to eliminate any unpleasant odor, then remove and drain well.

Step 2: Prepare the herbs. Gently rinse Bai Zi Ren (Platycladi Semen, Chinese arborvitae seed) once with clean water to remove dust, no soaking required. Remove pits from Hong Zao (Jujubae Fructus, Chinese red jujube) and slice, or keep whole as needed. Slice Sheng Jiang (Zingiberis Rhizoma Recens, fresh ginger). If using Fu Ling (Poria, tuckahoe), soak in warm water for 10 minutes in advance, then cut into small pieces.

Step 3: Blanching to remove odor. Add sufficient clean water to the pot and place the pig heart slices in. Bring to a boil over high heat and continue boiling for 2–3 minutes. Skim off any foam, then remove the pig heart slices and rinse them thoroughly with warm water. This step effectively eliminates the strong odor from the pig heart, resulting in a clearer and purer soup.

Step 4: Slow-simmer into a soup. Take a clay pot or ceramic stew pot, place the blanched pork heart slices, Semen Platycladi (Platycladus orientalis seeds), Fructus Jujubae (red dates), ginger slices, and Poria cocos together, and add sufficient fresh water (about 1500 ml). Bring to a boil over high heat, then reduce to low heat, cover with a lid, and simmer for 1.5–2 hours until the pork heart is tender and the soup turns milky white. Add an appropriate amount of salt for seasoning 10 minutes before turning off the heat, stir well, and serve.

Step Five: Strain and Serve. Use a fine-mesh strainer to remove the herb residue, retaining only the clear decoction for drinking. Alternatively, you may keep the sliced pig heart and red dates (Fructus Jujubae) to consume along with the broth. Pour into a bowl and allow to cool slightly before enjoying. For best results, if time permits, use a double-boiling pot (double-boiler) to maximize retention of both medicinal effects and original flavor.

Drinking Tips

1. The best time to consume is one hour after dinner or 1.5 hours before bedtime. At this time, the body’s Yang Qi converges and Yin Qi gradually prevails, allowing the calming effect of Semen Platycladi (Chinese arborvitae seed) and Pig Heart Soup to take better effect, helping to induce stable sleep. It is recommended to consume 2-3 times per week for four consecutive weeks as one regulation cycle.

2. When consuming, it is advisable to pair with light vegetables or congee, and avoid eating greasy, pungent, or raw-cold foods simultaneously to prevent compromising the absorption of medicinal effects. Discontinue use during a common cold or gastrointestinal discomfort, and resume only after the body has recovered.

3. Although Platycladus Seed and Pork Heart Soup (Bai Zi Ren Zhu Xin Tang) is beneficial, it should not be consumed in excess. A single serving of 200-300 ml is appropriate, with half the amount for children. If you are taking sedative-hypnotic Western medications, it is advisable to consume the soup at least 2 hours apart, or under a physician’s guidance. For pregnant women, nursing mothers, and individuals with allergic tendencies, start with a small amount on first consumption, and continue normal use only after observing no adverse reactions.
