"It is simply delicious."

If we are to believe what journalism tells us, people in Albany during the 19th century would go to slaughterhouses to drink the blood of freshly killed animals for its salubrious effects. From the September 18, 1881 Brooklyn Daily Eagle:

“A reporter of the Albany Evening Journal who has visited the abattoirs in that city, writes as follows of the persons who gather there to drink blood:

Several people, as soon as the throat was cut with sleeves uprolled and grasping a glass, hurried over to the hanging carcass and holding the goblets in turn under the ruby stream, filled their glasses and then drank of the steaming liquid. One, a middle aged man, seemed old in the business, for he threw the contents of the glass off at one draught. Another threw some salt in his glass before drinking, while another could hardly make up his mind whether or not to drink it. At last he shut his eyes and then after three or four efforts succeeded in downing about half a glassful. The reporter approached one of the butchers after he had finished dressing the carcass on which he was at work, and asked, ‘Do the same persons come every day?’ ‘No, they come two or three times a week on the average,’ was the reply. ‘Do any women ever come?’ ‘Yes, there used to be one young girl, but the last I saw of her she seemed to be getting fleshy and has stopped coming altogether.’

"It is richer than the richest of cream."

One of the invalids was then approached and asked, ‘How do you like blood drinking?’ ‘Well, I’ll tell you. At first when the doctor told me I would have to drink warm bullock’s blood or die, I told him that I preferred the latter, but I reconsidered my thought and came up to the slaughterhouse. I thought at first I could not touch it, and the sight of killing sickened me. But I soon overcame that feeling, and when I raised the first glass to my lips I spilt the contents over me. Next time I shut my eyes and drank it down. It tasted like rich milk, and if I kept my eyes shut, I would have not the known the difference.’ Another one of the drinkers was asked how it tasted. ‘How does it taste?’ said he. ‘It is richer than the richest of cream. It is simply delicious and a drink not to be compared with any potion extant. It is simply the elixir of life. You can feel its strength as it spreads through your veins. If it hadn’t been for its strengthening qualities I would have been dead three years ago.'”
