What the texts say
Charaka calls this matra viruddha, incompatibility by quantity, so the clause is about equal measure. Sushruta (Sutra 20.15) also says not to eat honey and ghee equal in measure. The Ashtanga Hridaya (Sutra 7.40) goes further: even unequal parts are incompatible if rainwater is drunk after them. None of the three gives a reason, or says whether "equal" means by weight or by volume.[1][2][3]
The modern view
Two rat studies disagree, and neither compared equal with unequal amounts, which is the point of the rule. In a 2020 study, 24 rats got honey, ghee, a 1:1 mix or nothing for 60 days. The mix group gained no weight over the 60 days, while the control rats doubled theirs. It also lost hair, had red ear patches, mild liver inflammation and a higher SGPT, a liver enzyme (58 against 44 IU/L). But the mix group was given about twice the volume of the single-food groups and started out heavier. In a 2010 study, rats fed honey mixed with ghee for six weeks showed no change in food intake, weight gain or organ weights.[4][5]

Heated honey (garam shahad)
Charaka says hot honey leads to death. Two rat studies of heated honey give mixed results, and no study we found has tested it in people.
FoodCurd and ghee
In Charaka, ghee is one of the things curd should be eaten with, not a pair to avoid. No study we found has tested the rule.
FoodCold water after ghee
Charaka says taking cold things after drinking ghee is incompatible. The rule is about ghee, not every meal, and no study we found tests it.
FoodMeat and honey
Charaka says not to eat the meat of domestic, marsh or water animals together with honey. No study we found tests the rule.
