The Concept of 'Hot' and 'Cold' in Traditional Medicine
The idea that foods have 'hot' or 'cold' properties is central to traditional healing systems such as Ayurveda and Traditional Chinese Medicine (TCM). This doesn't refer to the food's physical temperature but rather its energetic effect on the body after digestion. 'Hot' foods are considered to increase metabolism, improve circulation, and generate internal warmth. Conversely, 'cold' foods are believed to have a cooling, soothing effect on the body. Balancing these two energies, or 'doshas' in Ayurveda, is seen as key to maintaining optimal health.
Which Seeds Are Hot in Nature?
Several seeds are widely recognized for their warming or heating properties. These are often used in winter months or for individuals with a 'cold' constitution to boost internal heat.
- Sesame Seeds (Til): A staple in winter diets, sesame seeds are considered very warming and are prized for their ability to generate heat and energy. They are rich in healthy fats, protein, and minerals like magnesium and iron. Consuming them, often with jaggery, is a traditional practice to ward off the cold.
- Fenugreek Seeds (Methi Dana): These small, amber-colored seeds are well-known in Ayurveda for their heating nature. They are commonly used to improve digestion, relieve respiratory issues like cough and congestion, and stimulate metabolism. However, some sources also note that soaking them overnight may reduce their heating potency, making them beneficial for cooling in summer.
- Carom Seeds (Ajwain): Known for their pungent, bitter taste and aroma similar to thyme, carom seeds are potently heating. They contain thymol, an active compound with antibacterial and antifungal properties that also aids digestion by increasing the flow of stomach acids. Their warming effect is beneficial for treating cold-related ailments and indigestion.
- Mustard Seeds (Sarson): These seeds are very hot in nature and are known to generate heat internally. The sulfur-based compound, allyl-isothiocyanate, gives them their pungent, warming property. Mustard seeds are used in cooking and their oil for body massage to keep warm in winter.
- Black Cumin Seeds (Kalonji): Often called black seed or Nigella sativa, Kalonji is known for its medicinal properties and is considered a warming seed. It is packed with antioxidants and has been traditionally used to treat various ailments, from boosting immunity to improving digestive health.

Which Seeds Are Cooling in Nature?
Alongside their warming counterparts, several seeds are prized for their cooling effects, ideal for summer or balancing excess internal heat.
- Sabja Seeds (Basil Seeds): These small black seeds are a popular natural coolant, especially in tropical regions. When soaked in water, they swell up and develop a gel-like texture, which is often added to summer drinks like falooda or lemonade to help reduce body heat and aid digestion.
- Fennel Seeds (Saunf): With a sweet, licorice-like flavor, fennel seeds are known for their cooling effect. Chewing a few after a meal is a common practice to aid digestion and freshen breath, while drinking fennel tea can help reduce body heat.
- Coriander Seeds (Dhaniya): Both the seeds and leaves of coriander are considered cooling. Soaking coriander seeds overnight and drinking the water in the morning is an excellent way to flush out toxins and reduce excess body heat.
- Chia Seeds: These seeds are rich in antioxidants and omega-3 fatty acids. When soaked, they form a gelatinous texture that helps hydrate and cool the body. Chia seed drinks with lemon and honey are a popular way to combat heat and sunstroke.
How to Safely Incorporate Hot Seeds into Your Diet
- Use in Cooking: Add small quantities of fenugreek or carom seeds to curries, stews, and spice mixes. Toast sesame seeds to sprinkle over dishes or blend them into dressings and sauces.
- Make Herbal Teas: Boil seeds like fenugreek or carom with water to create a warming herbal tea, which can be particularly soothing for respiratory issues.
- Consume in Moderation: As with any potent ingredient, moderation is key. Overconsumption of hot seeds can lead to an increase in internal body heat, which might cause discomfort, especially for individuals with a 'hot' constitution or in warm weather.
- Balance with Cooling Foods: To prevent an excessive heating effect, balance your intake of hot seeds with cooling foods and drinks like cucumbers, melons, or basil seeds.
Conclusion
The traditional classification of seeds as 'hot' or 'cold' offers a valuable framework for understanding their effects on our bodies and leveraging their benefits. Seeds like sesame, fenugreek, and carom, which are hot in nature, are excellent for boosting internal warmth, aiding digestion, and supporting immunity, especially in colder months. By incorporating these potent seeds mindfully, you can utilize ancient wisdom to promote better health and internal balance. As always, for specific health concerns, it's wise to consult a healthcare professional.

Additional Insights
- Capsaicin Confusion: A common misconception is that the seeds of chili peppers are the hottest part. In reality, the heat comes from capsaicin, a compound concentrated in the white pith or ribs of the pepper, not the seeds themselves.
- Winter Benefits: The warming properties of seeds like sesame and fenugreek are why they are staples in traditional winter sweets and snacks, such as
til ke ladooandgajak, providing energy and warmth. - Ayurvedic Constitution: The appropriate use of hot or cold seeds depends on an individual's unique constitution, or
dosha. An Ayurvedic practitioner can help determine the right balance for your body type.
