Persistent allergies can indeed be a challenge, and Ayurveda offers several strategies to help balance the body’s response. Based on your symptoms - sneezing, itching, rashes, watery eyes and nose, urticaria - it appears there might be an imbalance in the ‘Kapha’ and ‘Pitta’ doshas.
First, consider prioritizing your diet. Avoid food that increases Kapha and Pitta, such as cold, oily, and spicy foods, as they may exacerbate your symptoms. Favor light, warm, and easily digestible foods; include spices like cumin, turmeric, ginger, and coriander in your meals, as they can help stimulate digestion and pacify the doshic imbalances.
You could try an herbal remedy like Haridra (Turmeric) due to its anti-inflammatory and anti-allergic properties. Incorporate it in warm milk or with honey to help manage allergic symptoms. Similarly, Neem is beneficial for skin-related issues due to its cooling nature. A daily dose of Ayurvedic Chyawanprash can help boost immunity.
Lifestyle has a significant role too. Create a routine that includes practices like Nasya, the application of medicated oils in the nostrils; Anu taila is often recommended and used in the morning to clear nasal passages and prevent allergies attacks. Moreover, adopt Yoga and Pranayama such as Anulom Vilom, which enhance lung capacity and aid in respiratory health.
For stress management - an underlying aggravator of allergies, try meditation and cooling breathing techniques like Sheetali pranayama.
Determining the IgE normalization period can be variable; for some, it might take weeks, for others, even months of consistent lifestyle and dietary modifications. It’s essential to monitor and adapt as you go, ideally under the guidance of a skilled practitioner.
Finally, be sure to consult with an ayurvedic doctor too. Your condition seems chronic, and an expert can provide a comprehensive approach tailored specifically for you. It’s always good to have somebody keeping an eye on your progress.
