Everything You Need to Know About the Pho Sawtooth Herb: Benefits, Flavour, and More
If you have ever sat down to a steaming bowl of traditional Vietnamese noodle soup, you have likely encountered the long, serrated, and vibrantly green leaves of the Pho Sawtooth Herb. Known for its intense aroma and robust flavour, this herb is much more than a simple garnish. It is a cornerstone of Southeast Asian cuisine and a powerhouse of nutrition.
Often referred to by its Vietnamese name, Ngò Gai, or scientifically as Eryngium foetidum, this plant is frequently mistaken for its cousin, cilantro (coriander). However, the Pho Sawtooth Herb offers a deeper, more earthy profile that holds up remarkably well under heat. In this guide, we will explore why this herb is a must-have in your kitchen and how its medicinal properties can support your wellbeing.
What Exactly is the Pho Sawtooth Herb?
The Pho Sawtooth Herb is a tropical perennial plant native to Mexico, Central, and South America, though it has become an indispensable staple in Vietnamese, Thai, and Caribbean cooking. It is often called long coriander or Mexican coriander because of its similar scent profile to common coriander, though it is significantly more potent.
The plant is easily recognisable by its long, lance-shaped leaves with “toothed” or serrated edges. Unlike common coriander, which can wilt the moment it touches hot broth, the aromatic leaves of the sawtooth variety are tough enough to be simmered without losing their character. This durability is why it is the preferred coriander alternative for slow-cooked dishes like Pho.
Sawtooth Herb vs. Cilantro: What Is the Difference?
While they share a similar chemical compound called decenal, which gives them that “soapy” or citrusy scent, they are quite different in application and intensity. If you find common coriander too mild or “soapy,” you might actually prefer the more balanced, savoury notes of the Pho Sawtooth Herb.
| Feature | Pho Sawtooth Herb (Culantro) | Common Coriander (Cilantro) |
|---|---|---|
| Leaf Shape | Long, serrated, and tough. | Small, delicate, and feathery. |
| Flavour Intensity | Very strong; earthy and pungent. | Mild to moderate; citrusy. |
| Heat Tolerance | High; retains flavour when cooked. | Low; usually added at the end. |
| Primary Names | Ngò Gai, Culantro, Recao. | Cilantro, Chinese Parsley. |
The Surprising Health Benefits of Pho Sawtooth Herb
Beyond its culinary uses, the Pho Sawtooth Herb has been used for centuries in herbal remedies across the globe. Modern science is beginning to catch up with traditional wisdom, identifying a range of phytochemicals that contribute to its health-promoting status.
1. Support for Digestive Health
In many cultures, Ngò Gai is brewed into a tea to soothe stomach aches and improve digestive health. The leaves contain compounds that act as carminatives, helping to reduce gas and bloating. The Mayo Clinic highlights that incorporating fresh herbs into your diet is an excellent way to add flavour without the need for excess salt or fats.
2. Potent Anti-inflammatory Properties
The Pho Sawtooth Herb is rich in flavonoids and phenolics. Research published on PubMed suggests that extracts from *Eryngium foetidum* possess significant anti-inflammatory effects. This makes it a valuable addition to a diet aimed at managing chronic inflammation. As one of the many anti-inflammatory herbs available in nature, it may help in reducing swelling and pain associated with various conditions.
3. Rich in Antioxidants
Oxidative stress is a primary driver of ageing and disease. The Pho Sawtooth Herb is packed with vitamins A, B, and C, alongside essential minerals like calcium and iron. According to Medical News Today, antioxidants are crucial for neutralising free radicals in the body, protecting your cells from damage.
How to Utilise Sawtooth Herb in Your Kitchen
While it is the star of Vietnamese Pho, you can utilise this versatile herb in various ways to elevate your cooking. Here are a few ideas:
- Pho Garnish: Finely shred the leaves and serve them alongside basil, lime, and chillies to be added to the hot soup.
- Marinades: Pulse the leaves with garlic, ginger, and oil to create a vibrant marinade for grilled meats or tofu.
- Stir-fries: Add chopped sawtooth herb during the last minute of stir-frying to maintain its crunch and aroma.
- Salsas and Pestos: Substitute common coriander with a smaller amount of Pho Sawtooth Herb for a more intense flavour profile.
When cooking, remember that Culantro benefits from being chopped finely. Because the leaves are more fibrous than other Vietnamese herbs, a fine chiffonade ensures the texture isn’t overwhelming for the diner.
Selection and Storage Tips
To get the most out of your Pho Sawtooth Herb, you need to know how to select and store it correctly. You can usually find it in specialised Asian or Caribbean grocers.
- Look for Colour: Choose leaves that are deep green without any yellowing or dark, slimy spots.
- Check the Aroma: A fresh bunch should have a strong, punchy scent immediately.
- Storage: Wrap the unwashed leaves in a damp paper towel and place them in a reusable silicone bag in the fridge. They generally last longer than common coriander—up to a week or more.
- Freezing: You can also chop the leaves and freeze them in ice cube trays with a little water or oil for future use in stews.
For those interested in sustainable living, the Royal Horticultural Society provides excellent resources on growing your own herbs at home, which ensures you always have a fresh supply of aromatic leaves.
Safety and Considerations
While the Pho Sawtooth Herb is generally safe for consumption, always consult with a healthcare professional before using concentrated herbal extracts, especially if you are pregnant or breastfeeding. The World Health Organization emphasises the importance of using traditional medicines safely and evidence-based.
Some individuals may have an allergic reaction to plants in the Apiaceae family (which includes carrots and celery). If you are trying it for the first time, start with a small amount to see how your body reacts.
