Chinese Yam & Goji Berry Pig Brain Soup: Brain Health Recipe

Chinese Yam and Goji Berry Pig Brain Soup: A Medicinal Diet Primer

Introduction to Medicinal Food

“Chinese Yam and Goji Berry Pig Brain Soup” is a classic medicinal diet originating from Lingnan folk tradition, combining nourishing and therapeutic effects. Chinese yam (Dioscorea opposita) and goji berries (Lycium barbarum) are both food and medicinal ingredients. Cooked together with pig brain, the soup has a milky white color, smooth texture, and sweet aroma. Based on the principle of “like nourishes like,” this soup is particularly favored by individuals focused on brain health. In traditional Chinese medicine, pig brain is cold in nature, sweet in taste, and enters the Kidney meridian and brain marrow. It nourishes the bone marrow and benefits deficiency-related fatigue. Chinese yam gently tonifies the Spleen, Lung, and Kidney. Goji berries are adept at nourishing the Liver and Kidney, benefiting essence and brightening the eyes. Combined, this soup can regulate symptoms such as dizziness and forgetfulness caused by overthinking and late-night mental strain, as well as help improve sub-health conditions like soreness and weakness of the lower back and knees, insomnia, and dream-disturbed sleep. Modern nutritional science has also confirmed that Chinese yam is rich in mucoprotein and polysaccharides, goji berries contain abundant Lycium barbarum polysaccharides and zeaxanthin, and pig brain provides lecithin and cephalin, all of which positively support the nervous system and memory function.

Efficacy of Medicinal Diet

Benefit intelligence and strengthen the brain, calm the spirit and settle the mind.

Pig brain is rich in lecithin and cephalin, which are essential components of neuronal cell membranes and help improve memory and concentration. Chinese Yam (Dioscorea opposita) contains choline and various amino acids that promote brain metabolism, while Goji Berry (Lycium barbarum) provides betaine, which has a calming and spirit-settling effect. This soup is particularly beneficial for office workers and students who engage in prolonged mental work, as well as middle-aged and elderly individuals experiencing memory decline.

Nourish the Liver and Kidney, nourish the Blood and improve vision.

Goji berry is a key herb for nourishing the liver and kidneys, capable of enriching liver blood and replenishing kidney essence, thereby relieving blurred vision, dry eyes, dizziness, and tinnitus caused by liver-kidney yin deficiency. Chinese yam strengthens the spleen and consolidates the kidneys, enhancing the yin-nourishing effect of goji berry. Together, they make the soup beneficial for brain health while also supporting eye care and anti-fatigue.

Fortify the spleen and supplement qi, strengthen the sinews and bones.

Chinese yam (Dioscorea opposita), white in color, enters the Lung (LU) meridian, and sweet in taste, returns to the Spleen (SP) meridian. It can strengthen the Spleen, boost Qi, and secure and astringe to stop diarrhea. For individuals with Spleen deficiency, poor appetite, and fatigue, this soup can gently enhance digestive and absorptive functions, thereby improving overall nutritional status. The calcium, phosphorus, and collagen in pig brain also help to strengthen bones.

Functions of Traditional Chinese Medicine

Supplement the marrow and nourish the brain, benefit deficiency and fatigue.

Traditional Chinese Medicine theory holds that “the brain is the sea of marrow.” The Kidney governs the bones and produces marrow; when marrow is abundant, the brain is healthy. Pig brain directly enters the Kidney Meridian (KI) and the sea of marrow, replenishing essence and marrow. It has a direct tonifying effect on dizziness, tinnitus, and memory decline caused by overexertion and deficiency of essence and blood. Huai Shan (Chinese yam, *Dioscorea opposita*) and Gou Qi (goji berry, *Lycium barbarum*) assist in tonifying the Kidney and consolidating essence, ensuring that the supplementation does not cause stagnation.

Gently tonify the Triple Energizer, harmonize Yin and Yang.

Huai Shan (Dioscorea opposita, Chinese Yam) is neutral in nature and enters the Spleen, Lung, and Kidney meridians (SP, LU, KI). It can tonify Lung qi in the upper jiao, strengthen Spleen function (Spleen qi) in the middle jiao, and secure Kidney essence in the lower jiao. Gou Qi (Lycium barbarum, Goji berry) is neutral to slightly warm in nature and enters the Liver and Kidney meridians (LR, KI). It specializes in nourishing yin and blood. Zhu Nao (pig brain) is cold in nature and can offset the slight warmth of Gou Qi, making the entire formula warm but not drying. The combination of these three herbs harmonizes the Spleen, Lung, Liver, and Kidneys, balancing yin and yang. It is especially suitable for individuals under long-term stress who present with a pattern of “deficiency with intolerance of tonification” (虚不受补).

Nourish the heart and calm the spirit, and restore coordination between the heart and kidney.

This decoction, by supplementing kidney essence and nourishing liver blood, indirectly facilitates the descent of heart fire and the ascent of kidney water, thereby ameliorating insomnia, excessive dreaming, and restlessness due to heart-kidney non-interaction. Diosgenin from Dioscorea opposita (Chinese yam) exhibits sedative properties, while Lycium barbarum polysaccharides from Lycium barbarum (goji berry) modulate neurotransmitter activity; together, they support the restoration of deep sleep.

Indications

• Brain workers, such as programmers, designers, researchers, and students, who engage in prolonged mental exertion, may suffer from dizziness, forgetfulness, and poor concentration. This soup helps nourish the brain.
• Middle-aged and elderly people: With aging, symptoms such as memory decline, soreness and weakness of the lower back and knees, and vision loss may occur. This soup can nourish the Liver and Kidney and delay brain function decline.
• For postpartum or post-surgical individuals with body weakness: due to blood loss or consumption leading to Qi and Blood Deficiency, spirit fatigue and lack of strength, and insomnia, this soup gently tonifies and helps restore physical strength.
• For people who stay up late and experience high stress: Frequently staying up late consumes and damages yin blood, leading to dry mouth, dry eyes, and irritability. This soup can nourish yin and moisten dryness, calm the spirit and settle the mind.

Contraindicated populations

• Patients with hyperlipidemia and hypercholesterolemia: Pig brain has a high cholesterol content (approximately 2500 mg per 100 grams), so it should be avoided or its consumption strictly limited.
• For those with internal exuberance of Dampness-Heat and profuse phlegm with cough: Pig brain is cloying and rich, while Gouqi (Lycium barbarum fruit) is sweet and moistening. They may promote Dampness and engender Phlegm, aggravating symptoms such as chest oppression and a thick, greasy tongue coating.
• In the case of common cold with fever and acute inflammation, tonification should be avoided during external pathogen invasion to prevent trapping the pathogens inside and delaying recovery.
• Pregnant women and children: Pig brain is cold in nature and may contain trace amounts of heavy metals; use with caution in pregnant women and children. If consumption is necessary, reduce the amount of pig brain and increase the proportion of Chinese yam.
• For those allergic to animal viscera: Pig brain is an animal organ, so individuals with allergic constitution should use caution when consuming it.

Ingredient Formula Proportions (Detailed Grams or Quantities)

• Fresh pig brain: 2 units (approximately 150–200 g; each brain about 80–100 g). It is recommended to select fresh pig brains and remove the surface blood vessels.
• Dried Chinese yam (Dioscorea opposita) slices: 30 g (or fresh Chinese yam 150 g). Dried Chinese yam releases its therapeutic properties more easily, while fresh Chinese yam has a smoother and stickier texture.
• Ningxia Lycium barbarum (Goji berry): 15 g (approximately a small handful). Plump, bright red berries are preferred.
• Fresh Ginger (Zingiber officinale): 5–6 slices (approx. 15 g). Removes fishy odor and disperses cold, harmonizes the medicinal properties.
• Red dates (Ziziphus jujuba): 3–4 pieces (approx. 20 g). Tonifies the middle burner and supplements qi, and enhances the sweet flavor of the soup.
• Clear water: 1500–1800 ml (approximately 6–7 bowls of water).
• Salt: 2–3 grams (for final seasoning). May also be omitted to retain its original flavor.

Preparation Method (Step by Step)

1. Preprocess the pig brain: Place the fresh pig brain in a large bowl, add enough clean water to fully submerge it. Use a toothpick or fine needle to gently remove the blood vessels and thin membranes on the surface (this step is crucial to eliminate any fishy odor). Change the water twice, then drain and set aside.
2. For preparing Chinese yam (Dioscorea opposita): If using dried yam slices, soak them in warm water for 20 minutes in advance. If using fresh yam, peel it first, then cut into rolling chunks, and immediately soak in diluted vinegar water to prevent oxidation.
3. Other ingredient preparation: Quickly rinse Goji berries (Lycium barbarum) once under running water; wash and pit Red dates (Ziziphus jujuba); slice Fresh ginger (Zingiber officinale).
4. Blanch to remove fishy odor: Bring a sufficient amount of water to a boil in a pot. Add the pig brain, 2 slices of fresh ginger (Zingiber officinale), and 1 teaspoon of cooking wine (rice wine). Blanch for 1–2 minutes until the surface of the brain turns white. Remove and rinse off any foam with warm water.
5. Place the blanched pig brain, Chinese yam (Dioscorea opposita), red dates (Ziziphus jujuba), and the remaining ginger slices into a clay pot or soup pot. Add 1500 ml of water. Bring to a boil over high heat, skim off any foam, then reduce to low heat and simmer for 40–50 minutes.
6. Add Lycium barbarum (Goji Berry): 10 minutes before turning off the heat, add the Goji berries and continue simmering on low heat. Goji berries should not be cooked for too long, to avoid excessive sourness and loss of nutrients.
7. Seasoning and finishing: Turn off the heat and add salt (optional), gently stirring with a spoon until dissolved. Pour into a bowl and garnish with a sprinkle of chopped scallions or cilantro (optional).

Drinking Tips

• Best consumption time: Recommended to be taken warm around 3–5 PM (Shen period, when the Bladder Meridian is active) or one hour before bedtime. During the Shen period, the body’s qi and blood flow into the Bladder Meridian, making it more effective for tonifying the Kidney and benefiting the Brain. Taking it before sleep helps calm the spirit and promote restful sleep.
• Frequency and dosage: 1–2 times per week is sufficient. Do not consume continuously for more than 4 weeks. Pig brain is high in cholesterol and should not be consumed in excess. Each serving of soup should be about 200–250 ml, and the pig brain can be eaten in two portions.
• Ingredient substitution and adjustment: If concerned about cholesterol, reduce pig brain by half, increase Chinese yam (Dioscorea opposita) to 50 grams, and add half a block of tofu (about 100 grams) for plant protein. For those with a Cold pattern, add 3–5 grams of longan (Dimocarpus longan) before removing from heat.
• Storage method: After drinking, strain out the pig brain and herbs, keeping only the liquid soup refrigerated (for no more than 24 hours). Before drinking again, heat thoroughly, but do not repeatedly bring to a boil.
