Which herb is used for heart conditions and edema, with diuretic and nervine actions?

• A. Prunus africana
• B. Selenicereus grandiflorus
• C. Rhamnus frangula
• D. Quercus rubra

Answer: (B)

When edema is tied to heart problems, you want an herb that can support heart function, help move excess fluid, and calm the nerves often involved in cardiac distress. Selenicereus grandiflorus fits this profile because it’s described as a cardiotonic herb with diuretic and nervine actions. The diuretic effect helps reduce fluid overload, easing edema, while the nervine action calms nervous arousal that can accompany palpitations or anxiety, and the cardiotonic aspect supports the heart’s pumping during strain. This combined activity targets both the circulatory issue (fluid buildup) and the nervous symptoms that accompany heart conditions. The other options don’t provide this same mix: one is mainly used for urinary or prostatic symptoms, another is a laxative, and the last is an astringent used for GI issues, without the diuretic and nervine support needed for heart-related edema.
