Kaffir Lime: A Citrus Full of Flavour and Benefits

Kaffir lime, also known as Citrus hystrix, is a small, bumpy-skinned citrus fruit native to Southeast Asia. Much more than an exotic ingredient, this unique fruit is prized in both cooking and traditional medicine for its intense aroma and natural health benefits.

At La Plantation, we showcase the very best of this citrus by offering only its leaves and zest, harvested at peak ripeness and processed the same day to preserve their full flavour and freshness.

What is Kaffir Lime?

Known as “kaffir lime” or “makrut lime,” this tropical citrus belongs to the same family as the lime but is easily recognised by its knobby green skin and intensely fragrant oils. Its flavour recalls lemongrass, verbena, and ginger, offering a complex, aromatic experience unlike any other.

Originally from Indonesia (specifically the island of Sumbawa), kaffir lime has spread across Southeast Asia and is an essential part of Cambodian cuisine. Unlike regular citrus, the fruit is rarely eaten whole. Instead, it is the zest and leaves that are the stars, offering more concentrated and vibrant aromas.

Our kaffir lime leaves and zest are carefully harvested and dehydrated on the same day to lock in freshness. The leaves can be used whole or finely sliced to add depth to curries, soups, and broths.

The kaffir lime zest is perfect for elevating desserts, teas, or fish dishes with its spicy-citrus notes. Beyond the kitchen, kaffir lime is also known for its traditional therapeutic uses.

Key Health Benefits of Kaffir Lime

Used for centuries in traditional Asian medicine, kaffir lime is recognised for its wide range of natural benefits. While scientific research is ongoing, many of its traditional applications have been highlighted in studies such as the one published by the African Journal of Biotechnology (2010).

Supports the Immune System

Kaffir lime is a natural source of vitamin C (43 mg), a powerful antioxidant that plays a key role in supporting the immune system. It helps protect cells from oxidative stress and contributes to immune defence. It also contains beta-carotene, a precursor to vitamin A.

Traditionally, the juice and essential oil are used to refresh and revitalise. They’re often added to immune-boosting blends, though they should always be used with care.

Digestive health

The zest and juice of kaffir lime contain natural compounds that can help stimulate digestion. In traditional use, it is valued for its carminative properties, helping reduce bloating and gas. It may also act as an antispasmodic, offering relief from cramps and stomach discomfort.

In Southeast Asian dishes like soups and curries, kaffir lime is a key ingredient not only for flavour but also for making meals easier to digest.

Natural Anti-Inflammatory

Kaffir lime leaves and essential oil are also used in traditional medicine to soothe inflammation-related pain, including sore muscles and joints. The oil is often applied in massage or compress form to reduce tension and swelling.

Kaffir lime is also valued for its anti-inflammatory effects. Its leaves and essential oil have long been used in traditional medicine to ease muscle aches, joint pain, and general inflammation-related discomfort. Often applied as part of herbal compresses, massage oils, or balms, the oil helps to reduce tension, support muscle recovery, and soothe tired limbs after physical exertion.

A citrus with key role in Khmer traditional medicine

In Khmer traditional medicine, kaffir lime is a staple remedy known for promoting overall well-being. In Cambodia, it is used in diverse ways to relieve physical discomfort, support digestion, and refresh the body and mind:

• Therapeutic baths and compresses: The aromatic leaves and zest are added to herbal baths or compresses to relieve muscle tension and calm irritated skin.
• Herbal teas and juices: These are commonly consumed to take advantage of kaffir lime’s gentle anti-inflammatory action, particularly for joint or digestive relief.
• Digestive aid: Frequently brewed into herbal infusions, kaffir lime is traditionally used to soothe indigestion, bloating, and stomach discomfort.
• Circulation and energy: The essential oil is massaged into the skin to help stimulate blood flow, ease fatigue, and promote a sense of energy and vitality.
• Immune support: Rich in vitamin C and antioxidants, it’s included in traditional teas and dietary regimens to naturally support the immune system.

These applications, deeply rooted in ancestral knowledge, are still widely practised today. While beneficial for daily wellness, they should not replace professional medical treatment when needed. Always consult a healthcare practitioner for persistent symptoms or conditions.

How to use Kaffir Lime in cooking

Kaffir lime can easily be integrated into your diet—especially in its zest or dried leaf forms. The zest has powerful aromas with hints of lemongrass and ginger, ideal for enhancing both sweet and savoury dishes. Try it in desserts such as pancakes with poached pears, or sprinkle it over grilled fish, soups, or pastries.

The leaves, a staple in Cambodian cuisine, add citrusy freshness to broths, curries, fish, and meat dishes. They also pair surprisingly well with fruit-based recipes.

Where to buy and how to choose Kaffir Lime

To get the most flavour and benefit, choose kaffir lime products that are ethically sourced and harvested at full maturity—like those from our farm in Kampot. Avoid imported “fresh” fruits picked too early, as they often lack aroma and are not always sustainably grown.

Opt for dried zest and leaves, which retain their essential oils and healthful properties when properly prepared. This ensures a product that’s rich in flavour and grown with respect for the land and local communities.

Skin Benefits of Kaffir Lime

Kaffir lime isn’t just good in your food—it also helps care for your skin. Thanks to its purifying and regenerative properties, it’s widely used in Southeast Asian beauty rituals to support clear, glowing skin.

• Citric acid in the fruit gently exfoliates and promotes cell renewal.
• Antioxidants found in the zest and leaves help soothe and protect sensitive skin.
• Essential oil has a refreshing, clarifying action. Used in creams or serums, it can help regulate sebum and improve skin tone.

Kaffir lime is a truly remarkable citrus. Whether you use it in your cooking, skincare, or wellness rituals, its vibrant scent and powerful properties make it a versatile ally for everyday health and pleasure.
