Can Buddhists Eat Onion and Garlic?

By Tim Yu · Updated 2026-06-27

Can Buddhists eat onion and garlic? Most do — but many East Asian Mahāyāna Buddhists avoid them. Across Theravāda Asia and among lay Buddhists everywhere, onion and garlic are ordinary food. But in Chinese, Korean, and Vietnamese Mahāyāna practice they belong to the “five pungent spices,” avoided because certain sūtras teach they inflame desire and anger and cloud meditation. So this is a real dietary discipline in one part of the Buddhist world — and no rule at all in another, a revealing corner of Buddhist ethics.

Most Buddhists eat them freely

Let us clear up the common half-truth first. There is no general Buddhist prohibition on onion and garlic, and no precept mentions them. The overwhelming majority of the world’s Buddhists — all of Theravāda South and Southeast Asia, and lay practitioners nearly everywhere — cook and eat them without a second thought. If you have eaten Thai or Sri Lankan Buddhist food, it was almost certainly full of garlic. The avoidance is specific to one tradition, and even there mainly to its monastics and its most devout laypeople.

The five pungent spices

That tradition is East Asian Mahāyāna, and the practice concerns the five pungent spices — in Chinese, the 五辛 (wǔ xīn), the “five acrid” vegetables (also called 五葷, wǔ hūn). The classic five are:

1. garlic
2. onion
3. chives
4. leeks
5. scallions (spring onions) — with asafoetida substituted in some lists.

This is why genuine Buddhist temple cuisine in China, Korea, and Vietnam is not only vegetarian but also entirely free of onion and garlic — a cooking tradition built around keeping the mind cool and clear.

Why the Śūraṅgama Sūtra says to avoid them

The best-known scriptural basis is the Śūraṅgama Sūtra, and its reasoning is specifically about meditation. It teaches that the five pungents, eaten cooked, increase sexual desire, and eaten raw, increase anger — stirring up precisely the passions a practitioner is working to calm. It adds two more colourful reasons: that their powerful smell drives away the protective gods (devas) and instead attracts hungry ghosts, and that they obstruct samādhi, meditative concentration. Whether one reads these literally or as vivid teaching images, the underlying point is consistent with the whole tradition: what you put in the body affects the mind, and a serious meditator removes even subtle agitators from the diet. For a lay Buddhist outside that tradition none of this is binding — but the underlying insight is worth borrowing: diet and mind are linked, and a calmer plate can make for a calmer sitting. Many who take up meditation seriously find, with no rule requiring it, that they naturally lighten and simplify what they eat.

A footnote: the nuns’ garlic rule

There is one small, often-misunderstood detail worth clearing up. The early Vinaya does contain a rule about garlic — Bhikkhunī Pācittiya 1 — but it is far narrower than it sounds. It arose when a lay supporter offered the nuns garlic from his field and one nun, Thullanandā, took a greedy, excessive amount, spoiling the man’s crop and his goodwill. The training rule that followed is about moderation and not abusing a donor’s generosity, not a doctrinal ban on garlic. It applies to nuns, in that spirit — and it is not the reason East Asian Mahāyāna avoids the five pungents (that is the Śūraṅgama, centuries and a continent away). So no: garlic is not forbidden to Buddhists in general; it is set aside by one tradition, for the sake of a quiet mind.
