Sea Grapes
Caulerpa lentillifera
Long before it appeared in modern seaweed salads, this bright green alga was gathered by hand along shallow tropical shorelines and eaten fresh as an everyday coastal food. In the Philippines it is known as lato or ar-arusip and is a familiar sight in local markets, while in Okinawa it goes by umi-budo and has been woven into the regional table for generations. Coastal communities have long valued it simply as a refreshing, mineral rich food from the sea, eaten raw with a splash of something sour to brighten its delicate brine.

Traditional preparations.
The classic way sea grapes are enjoyed across the Philippines, Okinawa, and much of maritime Southeast Asia, prized simply as a refreshing, mineral rich food rather than as a medicine.
Traditionally, a small handful of fresh sea grapes is rinsed briefly in cool water, then tossed with sliced tomato, a squeeze of calamansi or lime, and a drizzle of vinegar or light dressing just before eating.
Safety.
Sea grapes are a food rather than a medicinal herb and are safe to eat. Like other seaweeds they can concentrate iodine and trace heavy metals from the water they grow in, and since they're traditionally eaten raw, rinse them well and eat them promptly.
