For those new to vegetarianism, especially in Asia, one of the most confusing questions is: “Why are onions and garlic, which are plants, considered forbidden?” or “Why Avoid The Five Pungent Roots?” This is not just a matter of dietary preference but involves deep religious culture, physiological science, and social etiquette.
This article explores the true identity of these roots, from ancient Brahmin taboos to records in the Shurangama Sutra, and modern medical research on allicin and hormones. We also integrate related topics like Why Do People Go Vegetarian? and The Rainbow Diet to provide a complete knowledge base. Whether you are vegetarian for faith or health, you’ll find your answers here.
Identity Revealed: What Are the Five Pungent Roots?
Definition and Historical Origin
The prohibition originates from ancient Indian Brahmin dietary habits and was later adopted by Buddhism. It is recorded that the Buddha established this rule after monks who ate garlic refrained from listening to sermons to avoid offending others with their breath.
The Complete List of Five Pungent Plants
According to the Brahmajala Sutra, the five are: Garlic, Scallion, Leek, Chinese Onion, and Asafoetida. Here is their modern correspondence:
Characteristics: Bulb composed of multiple cloves, strongest odor.
Effect: High allicin content, strong antibacterial and blood pressure lowering properties.
Includes: Green onions, shallots.
Characteristics: Hollow tubular leaves, rich in Vitamin C and Potassium.
Includes: Garlic chives, yellow chives.
Characteristics: Flat leaves, rich in Beta-carotene and Folate.
Aliases: Rakkyo, Lucky.
Characteristics: Top looks like scallion, bottom like garlic. Often pickled.
Modern Equivalent: Onion (in most Chinese Buddhist contexts).
Characteristics: While Asafoetida is a distinct spice from India/Iran, “Onion” is generally treated as the fifth forbidden root in Taiwan.

Why Avoid The Five Pungent Roots? Three Major Reasons
1. Religious & Spiritual Perspective
The Shurangama Sutra states: “If eaten cooked, they are aphrodisiac; if eaten raw, they increase anger… The good spirits of the ten directions will stay far away due to the foul odor.”
For practitioners, consuming these roots may attract negative energies and hinder the practice of “Samadhi” (deep meditation). Read more on Moonpointer’s analysis.
2. Physiological Impact: The Science of Allicin
Scientific studies indicate that the concentrated sulfur compounds (like allicin) in these plants can affect hormones. They may stimulate the secretion of sex hormones, potentially increasing libido, which contradicts the goal of reducing desire in monastic life.
- Cooked (Aphrodisiac): Stimulates hormone secretion, potentially causing physiological impulses.
- Raw (Aggression): Raw spicy foods can stimulate the sympathetic nervous system, making one irritable or easily angered.
3. Social Environment: Breath and Atmosphere
These roots contain volatile sulfur compounds released through the breath and sweat glands, lasting 24-48 hours. In a communal meditation setting where purity is valued, strong body odor can disturb others’ focus.
Health Analysis: Benefits vs. Side Effects
Nutritional Value
From a modern medical perspective, these are superfoods. Garlic reduces cholesterol by 10-15% and is a potent antibiotic; onions are rich in quercetin for heart health; leeks are good sources of lutein.
Potential Side Effects
However, water can float a boat but also sink it. Excessive consumption can irritate the stomach.
| Risk Category | Potential Impact | High-Risk Groups |
|---|---|---|
| Digestive System | Hyperacidity, Acid reflux, Bloating | Ulcer or Gastritis patients |
| Drug Interaction | Prolongs clotting time, enhances diabetes meds | Those on anticoagulants or diabetics |
| Social Impact | Bad breath, Body odor | Service industry workers |

Health Impact on Vegetarians
Cardiovascular Protection
Vegetarians already have lower cardiovascular risks. Moderate intake of onions and garlic (if not religiously prohibited) can provide double protection through anti-thrombotic and blood pressure-regulating effects.
Immune System Boost
Sulfides in these roots activate macrophages, boosting immunity. For vegetarians prone to colds, cooked onion/garlic soup can act as a natural preventative measure, provided there are no religious restrictions.

We highly recommend “Toon Sauce” (香椿醬), known as “Vegetarian Scallion,” for its rich, savory aroma similar to onions/garlic.
