The Diverse Effects of Different Lily Species
Many plants are commonly referred to as “lily,” but their effects on the body vary significantly. It is essential to distinguish between edible and medicinal varieties and those that are highly toxic, such as lily-of-the-valley (Convallaria majalis). This guide focuses on the uses of Baihe, Madonna lily, water lily, and daylily, while providing a critical safety warning about poisonous types.
Baihe (Lilium brownii): The Medicinal Lily Bulb
In Traditional Chinese Medicine (TCM), the bulb of the Baihe lily is a classic nutraceutical valued for its complex chemical composition, which includes steroidal saponins, polysaccharides, and flavonoids. It is frequently used for its therapeutic effects on yin deficiency and related symptoms.
Key uses of Baihe:
- Moistens the lungs and relieves cough: Often used in herbal formulas to address coughs caused by lung dryness, fatigue, or other chest ailments.
- Calms the spirit and soothes the heart: Advocates report that lily bulb tea can calm the spirit and address symptoms like heart palpitations, anxiety, and insomnia.
- Enhances immunity: Some studies suggest that lily polysaccharides can boost immune function by promoting the proliferation of immune cells and enhancing macrophage activity.
- Antioxidant and anti-inflammatory properties: The bioactive components in lily bulbs, particularly phenols and flavonoids, have shown antioxidant and anti-inflammatory activities, which may help mitigate cellular damage.
Madonna Lily (Lilium candidum): Aiding Skin Health
Native to the Mediterranean, the Madonna lily has a long history in folk medicine, particularly for its topical applications. The bulb extract, in particular, is noted for its skin-benefiting properties.
How Madonna lily benefits the skin:
- Soothing and emollient effects: The bulb extract is commonly used in cosmetics for its softening and soothing properties, which can improve the appearance and texture of skin.
- Anti-inflammatory and antiseptic: Due to the presence of tannins, it can act as an astringent and possesses antiseptic qualities, making it suitable for treating skin conditions like acne, burns, and ulcers.
- Aids rejuvenation: It supports skin renewal by helping to eliminate toxins and providing a moisturizing effect, contributing to a more radiant complexion.
Water Lily (Nymphaea alba): Calming and Antioxidant Effects
Ancient civilizations cherished the water lily for its spiritual and medicinal significance. Modern research highlights its antioxidant and calming properties, which benefit both the body and mind.
Benefits of water lily:
- Stress and anxiety relief: Considered an adaptogen, certain water lilies can help soothe anxiety and stress, promoting a sense of calm and better sleep quality.
- Antioxidant protection: Water lily extract is packed with antioxidants that protect against oxidative stress, contributing to healthier, more vibrant skin.
- Moisturizing and soothing: It provides conditioning and moisturizing effects, helping to soothe rashes, irritations, and other skin problems.
Daylily (Hemerocallis): The Edible and Nutritious Vegetable
Often referred to as “Huang Huacai,” daylily flowers are a high-quality food source with a range of nutritional and medicinal properties. It is important to note that many other daylily varieties are for ornamental purposes only and not all are edible.
Nutritional and health benefits of daylilies:
- Rich in nutrients: Daylily buds contain protein, vitamin C, carotenoids, flavonoids, and dietary fiber.
- Supports digestive health: The dietary fiber and polysaccharides in daylilies can improve digestive function and promote a healthy intestinal environment by encouraging beneficial gut bacteria.
- Aids sleep and mood: Studies have shown that daylily extracts can improve sleep quality, reduce sleep latency, and exhibit antidepressant effects, potentially due to increasing neurotransmitter concentrations like serotonin.
Important Safety Warning: Know Your Lily Species
It is absolutely critical to understand that not all plants called “lily” are safe. Lily-of-the-valley (Convallaria majalis) is highly poisonous and consuming any part of it can cause severe symptoms, including digitalis-like cardiac toxicity. Symptoms can include an irregular heartbeat, nausea, vomiting, and in severe cases, be fatal. Always ensure that any plant used for medicinal or culinary purposes is correctly and safely identified. When foraging or purchasing herbal products, rely only on reputable sources. The same applies to household pets, as many lilies are toxic to cats and dogs.

Key Considerations and Conclusion
When considering what a lily can do for the body, the first step is accurate identification. For centuries, various true lily species, like the Baihe bulb, have served as valuable components of traditional medicine, offering respiratory relief and calming properties. Other types, such as the Madonna lily, have provided cosmetic and topical benefits. With growing interest in nutraceuticals, modern research is validating many traditional uses, exploring antioxidant, anti-inflammatory, and mood-boosting effects. However, the severe toxicity of certain species like lily-of-the-valley cannot be overstated. Understanding these distinctions is crucial for safe consumption and application. As always, consult a healthcare professional before using herbal remedies, especially if you have pre-existing conditions or are taking other medications.
