Cluster Fig (Ficus racemosa), also known as Udumbara in Ayurveda, has been traditionally used in Indian and Southeast Asian medicine for a variety of ailments, including goiter. In classical Ayurvedic texts, the bark and other parts of the tree are described as beneficial for conditions related to swelling and enlargement of glands, which would include goiter (thyroid gland enlargement). The use is primarily based on its purported anti-inflammatory and astringent properties. Specific Ayurvedic formulations may include Cluster Fig bark in decoctions or pastes intended to reduce glandular swellings.

However, there is minimal to no robust scientific evidence supporting the efficacy of Cluster Fig in the treatment of goiter. Modern research on Ficus racemosa has explored its antioxidant, anti-inflammatory, and antimicrobial activities, but studies directly assessing its impact on thyroid function or goiter in humans are lacking. There are no clinical trials or animal studies that conclusively validate its use for goiter by contemporary biomedical standards. Thus, its use for this condition is supported by traditional medical systems rather than scientific validation. The evidence rating is low (1/5) as it is based on historical references rather than experimental or clinical data.
