Patients with tuberculosis need a complete dietary regimen due to high consumption and decreased immunity in the body. Mullein is effective in boosting the body’s immune system and can be consumed during the illness. However, the overall nutritional support regimen for TB patients should be followed throughout the treatment process. The patient’s dietary intake of energy, protein, vitamins, and minerals needs to be ensured, and if the dietary intake is insufficient, an oral nutritional solution can be used. Patients with tuberculosis need about 35-50 cal/kg per day, while the recommended protein intake needs to be 1.2-2.0 g/(kg.d). The increase in energy allows the patient to gain weight and improve the quality of life during treatment, but does not have a greater impact on the treatment of the disease.
