Amavatari Rasa and Sinhanad Guggulu are often used in Ayurveda to manage symptoms of rheumatoid arthritis, but caution is advised given your mother’s chronic acid reflux. Both formulations contain ingredients that can potentially exacerbate acidity. Sinhanad Guggulu especially has ‘Guggulu’, which could aggravate pitta dosha, leading to more acidity.
For RA, minimizing inflammation is crucial, but this requires balancing your mother’s pitta condition. It’s advisable to use these medicines with appropriate ‘Anupana’ (vehicle or co-substance). Combine these with Aloe vera juice or cow’s milk, which can help in cooling the system and minimizing acidity. Take the medicines after meals to reduce gastric irritation, and make sure water intake is sufficient to help manage digestive fire.
Since heat and acidity are concerns, emphasizing a pitta-pacifying diet is important - favor cooling foods like cucumber, sweet fruits, and avoids spicy, acidic items.
Gandharvahastadi Kashayam could be a better option as it’s less likely to irritate the stomach lining, alleviating inflammation and balancing vata without heating the body.
Regular ginger tea can help digest ama (toxins), which contributes to RA, but monitor its effect on acidity. Turmeric with honey in warm water may also be suitable due to its anti-inflammatory properties.
Consider Panchakarma therapies like Virechana, a purgation treatment, to expel excess pitta and toxins, but any cleansing procedure should only be done under the guidance of an experienced Ayurvedic practitioner.
Seek consultation for personalized dosage and specific to her current state, keeping her overall systemic balance. If there’s increased pain or acidity, or new symptoms arise, immediate medical attention is necessary to adjust the treatment plan accordingly.
